The input pins, VIN+ and VIN-, should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance. Power-supply bypass capacitors are required for stability. Applications with noisy or high impedance power supplies may require additional decoupling capacitors to reject power supply noise. Connect bypass capacitors close to the device pins. RS IS VIN+ V+ 2.7 V to 18 V -16 V to 80 V VIN+ VIN- R1 R2 Load OUT INA193A RL Figure 1. INA193A Basic Connection Power Supply The input circuitry of the INA193A can accurately measure beyond its power supply voltage, V+. For example, the V+ power supply can be 5 V, whereas the load power supply voltage is up to 80 V. The output voltage range of the OUT terminal, however, is limited by the voltages on the power-supply pin. Accuracy Variations as a Result of VSENSE and Common-Mode Voltage The accuracy of the INA193A current shunt monitors is a function of two main variables: VSENSE (VIN+ - VIN-) and common-mode voltage, VCM, relative to the supply voltage, VS. VCM is expressed as (VIN+ + VIN-)/2; however, in practice, VCM is seen as the voltage at VIN+ because the voltage drop across VSENSE is usually small. 8 Submit Documentation Feedback Copyright (c) 2007-2013, Texas Instruments Incorporated Product Folder Links: INA193A-EP INA193A-EP www.ti.com SBOS400A - MAY 2007 - REVISED SEPTEMBER 2013 This section addresses the accuracy of these specific operating regions: Normal Case 1: VSENSE 20 mV, VCM VS Normal Case 2: VSENSE 20 mV, VCM < VS Low VSENSE Case 1: VSENSE < 20 mV, -16 V VCM < 0 Low VSENSE Case 2: VSENSE < 20 mV, 0 V VCM VS Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM 80 V Normal Case 1: VSENSE 20 mV, VCM VS This region of operation provides the highest accuracy. Here, the input offset voltage is characterized and measured using a two-step method. First, the gain is determined by (Equation 1). V OUT1 * V OUT2 G+ 100 mV * 20 mV (1) Where: VOUT1 = Output voltage with VSENSE = 100 mV VOUT2 = Output voltage with VSENSE = 20 mV The offset voltage is then measured at VSENSE = 100 mV and referred to the input (RTI) of the current shunt monitor, as shown in (Equation 2). V OSRTI (Referred-To-Input) + V G * 100 mV OUT1 (2) In the Typical Characteristics, the Output Error vs Common-Mode Voltage curve shows the highest accuracy for the this region of operation. In this plot, VS = 12 V; for VCM 12 V, the output error is at its minimum. This case is also used to create the VSENSE 20 mV output specifications in the Electrical Characteristics table. Normal Case 2: VSENSE 20 mV, VCM < VS This region of operation has slightly less accuracy than Normal Case 1 as a result of the common-mode operating area in which the part functions, as seen in the Output Error vs Common-Mode Voltage curve. As noted, for this graph VS = 12 V; for VCM < 12 V, the Output Error increases as VCM becomes less than 12 V, with a typical maximum error of 0.005% at the most negative VCM = -16 V. Low VSENSE Case 1: VSENSE < 20 mV, -16 V VCM < 0; and Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM 80 V Although the INA193A is not designed for accurate operation in either of these regions, some applications are exposed to these conditions; for example, when monitoring power supplies that are switched on and off while VS is still applied to the INA193A. It is important to know what the behavior of the devices will be in these regions. As VSENSE approaches 0 mV, in these VCM regions, the device output accuracy degrades. A larger-than-normal offset can appear at the current shunt monitor output with a typical maximum value of VOUT = 300 mV for VSENSE = 0 mV. As VSENSE approaches 20 mV, VOUT returns to the expected output value with accuracy as specified in the Electrical Characteristics. Figure 2 illustrates this effect using the INA195A and INA198A (Gain = 100).

Example for Low VSENSE Cases 1 and 3 (INA195A, INA198A: Gain = 100) Low VSENSE Case 2: VSENSE < 20 mV, 0 V VCM VS This region of operation is the least accurate for the INA193A. To achieve the wide input common-mode voltage range, these devices use two op amp front ends in parallel. One op amp front end operates in the positive input common-mode voltage range, and the other in the negative input region. For this case, neither of these two internal amplifiers dominates and overall loop gain is very low. Within this region, VOUT approaches voltages close to linear operation levels for Normal Case 2. This deviation from linear operation becomes greatest the closer VSENSE approaches 0 V. Within this region, as VSENSE approaches 20 mV, device operation is closer to that described by Normal Case 2. Figure 3 illustrates this behavior for the INA195A. The VOUT maximum peak for this case is tested by maintaining a constant VS, setting VSENSE = 0 mV and sweeping VCM from 0 V to VS. The exact VCM at which VOUT peaks during this test varies from part to part, but the VOUT maximum peak is tested to be less than the specified VOUT tested limit. 2.4 INA195, INA198 VOUT Tested Limit(1) VCM1 2.2 2.0 Ideal 1.8 VCM2 VOUT (V) 1.6 1.4 VCM3 1.2 1.0 VOUT tested limit at VSENSE = 0mV, 0 VCM1 VS.

Use a totem pole output buffer or gate that can provide sufficient drive along with 0.1-F bypass capacitor, preferably ceramic with good high frequency characteristics. This gate should have a supply voltage of 3 V or greater because the INA193A requires a minimum supply greater than 2.7 V. In addition to eliminating quiescent current, this gate also turns off the 10 A bias current present at each of the inputs. An example shutdown circuit is shown in Figure 4.

INA193A Example Shutdown Circuit Selecting RS The value chosen for the shunt resistor, RS, depends on the application and is a compromise between smallsignal accuracy and maximum permissible voltage loss in the measurement line. High values of RS provide better accuracy at lower currents by minimizing the effects of offset, while low values of RS minimize voltage loss in the supply line. For most applications, best performance is attained with an RS value that provides a full-scale shunt voltage range of 50 mV to 100 mV. Maximum input voltage for accurate measurements is 500 mV. Transient Protection The -16 V to 80 V common-mode range of the INA193A is ideal for withstanding automotive fault conditions ranging from 12-V battery reversal up to 80-V transients, since no additional protective components are needed up to those levels. In the event that the INA193A is exposed to transients on the inputs in excess of its ratings, then external transient absorption with semiconductor transient absorbers (zeners or Transzorbs) will be necessary. Use of MOVs or VDRs is not recommended except when they are used in addition to a semiconductor transient absorber. Select the transient absorber such that it will never allow the INA193A to be exposed to transients greater than 80 V (that is, allow for transient absorber tolerance, as well as additional voltage due to transient absorber dynamic impedance). Despite the use of internal zener type ESD protection, the INA193A- does not lend itself to using external resistors in series with the inputs since the internal gain resistors can vary up to 30% (if gain accuracy is not important, then resistors can be added in series with the INA193A inputs with two equal resistors on each input).

This is best illustrated when using the INA195A or INA198A (which are both versions using a gain of 100), where a 100 mV full-scale input from the shunt resistor requires an output voltage swing of 10 V, and a power-supply voltage sufficient to achieve 10 V on the output. RFI/EMI Attention to good layout practices is always recommended. Keep traces short and, when possible, use a printed circuit board (PCB) ground plane with surface-mount components placed as close to the device pins as possible. Small ceramic capacitors placed directly across amplifier inputs can reduce RFI/EMI sensitivity. PCB layout should locate the amplifier as far away as possible from RFI sources. Sources can include other components in the same system as the amplifier itself, such as inductors (particularly switched inductors handling a lot of current and at high frequencies). RFI can generally be identified as a variation in offset voltage or dc signal levels with changes in the interfering RF signal. If the amplifier cannot be located away from sources of radiation, shielding may be needed. Twisting wire input leads makes them more resistant to RF fields. Input Filtering An obvious and straightforward location for filtering is at the output of the INA193A; however, this location negates the advantage of the low output impedance of the internal buffer. The only other option for filtering is at the input pins of the INA193A, which is complicated by the internal 5-k + 30% input impedance; this is illustrated in Figure 5. Using the lowest possible resistor values minimizes both the initial shift in gain and effects of tolerance. The effect on initial gain is given by: GainError% + 100 * 100 5k W 5k W ) RFILT (3) Total effect on gain error can be calculated by replacing the 5-k term with 5 k - 30%, (or 3.5 k) or 5 k + 30% (or 6.5 k). The tolerance extremes of RFILT can also be inserted into the equation. If a pair of 100- 1% resistors are used on the inputs, the initial gain error will be approximately 2%. Worst-case tolerance conditions will always occur at the lower excursion of the internal 5-k resistor (3.5 k), and the higher excursion of RFILT - 3% in this case. Note that the specified accuracy of the INA193A must then be combined in addition to these tolerances. While this discussion treated accuracy worst-case conditions by combining the extremes of the resistor values, it is appropriate to use geometric mean or root sum square calculations to total the effects of accuracy variations. 12 Submit Documentation Feedback Copyright (c) 2007-2013, Texas Instruments Incorporated Product Folder Links: INA193A-EP INA193A-EP www.ti.com SBOS400A - MAY 2007 - REVISED SEPTEMBER 2013 RSHUNT << RFILTER LOAD VSUPPLY RFILT < 100 W RFILT < 100 W CFILT f-3dB f-3dB = 1 2p (2 RFILT) CFILT +5 V VIN+ VIN- R1 5 kW V+ R1 5 kW OUT INA193A RL Figure 5. Input Filter (Gain Error - 15% to -2.2%) Inside the INA193A The INA193A uses a new, unique internal circuit topology that provides common-mode range extending from -16 V to 80 V while operating from a single power supply. The common-mode rejection in a classic instrumentation amp approach is limited by the requirement for accurate resistor matching. By converting the induced input voltage to a current, the INA193A provides common-mode rejection that is no longer a function of closely matched resistor values, providing the enhanced performance necessary for such a wide common-mode range. A simplified diagram (shown in Figure 6) shows the basic circuit function. When the common-mode voltage is positive, amplifier A2 is active. The differential input voltage, (VIN+) - (VIN-) applied across RS, is converted to a current through a resistor. This current is converted back to a voltage through RL, and then amplified by the output buffer amplifier. When the common-mode voltage is negative, amplifier A1 is active. The differential input voltage, (VIN+) - (VIN-) applied across RS, is converted to a current through a resistor. This current is sourced from a precision current mirror whose output is directed into RL converting the signal back into a voltage and amplified by the output buffer amplifier. Patent-pending circuit architecture ensures smooth device operation, even during the transition period where both amplifiers A1 and A2 are active.

Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyers and others who are developing systems that incorporate TI products (collectively, "Designers") understand and agree that Designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products used in or for Designers' applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI's provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, "TI Resources") are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer's company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI's provision of TI Resources does not expand or otherwise alter TI's applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically described in the published documentation for a particular TI Resource. Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. TI RESOURCES ARE PROVIDED "AS IS" AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM, INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL, DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers' own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection.
