This makes the LMC7101 ideal for space and weight critical designs. The performance is similar to a single amplifier of the LMC6482/LMC6484 type, with rail-to-rail input and output, high open loop gain, low distortion, and low supply currents. The main benefits of the Tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards. The tiny amplifiers can be placed on a board where they are needed, simplifying board layout. Connection Diagram Figure 1. 5-Pin SOT-23 Top View These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Because they are easier to carry, many customers prefer smaller and lighter products. Height The height (0.056 inches, 1.43 mm) of the Tiny amp makes it possible to use it in PCMCIA type III cards. Signal Integrity Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier package, the Tiny amp can be placed closer to the signal source, reducing noise pickup and increasing signal integrity. The Tiny amp can also be placed next to the signal destination, such as a buffer for the reference of an analog to digital converter. Simplified Board Layout The Tiny amp can simplify board layout in several ways. First, by placing an amp where amps are needed, instead of routing signals to a dual or quad device, long pc traces may be avoided. By using multiple Tiny amps instead of duals or quads, complex signal routing and possibly crosstalk can be reduced. Low THD The high open loop gain of the LMC7101 amp allows it to achieve very low audio distortion--typically 0.01% at 10 kHz with a 10 k load at 5V supplies. This makes the Tiny an excellent for audio, modems, and low frequency signal processing. Low Supply Current The typical 0.5 mA supply current of the LMC7101 extends battery life in portable applications, and may allow the reduction of the size of batteries in some applications. Wide Voltage Range The LMC7101 is characterized at 15V, 5V and 3V. Performance data is provided at these popular voltages. This wide voltage range makes the LMC7101 a good choice for devices where the voltage may vary over the life of the batteries. INPUT COMMON MODE Voltage Range The LMC7101 does not exhibit phase inversion when an input voltage exceeds the negative supply voltage. Figure 62 shows an input voltage exceeding both supplies with no resulting phase inversion of the output. The absolute maximum input voltage is 300 mV beyond either rail at room temperature. Voltages greatly exceeding this maximum rating, as in Figure 63, can cause excessive current to flow in or out of the input pins, adversely affecting reliability. 18 Submit Documentation Feedback Copyright (c) 1999-2013, Texas Instruments Incorporated Product Folder Links: LMC7101 LMC7101Q LMC7101, LMC7101Q www.ti.com SNOS719F - SEPTEMBER 1999 - REVISED MARCH 2013 An input voltage signal exceeds the LMC7101 power supply voltages with no output phase inversion. Figure 62. Input Voltage A 7.5V input signal greatly exceeds the 3V supply in Figure 64 causing no phase inversion due to RI. Figure 63. Input Signal Applications that exceed this rating must externally limit the maximum input current to 5 mA with an input resistor as shown in Figure 64. Figure 64. RI Input Current Protection for Voltages Exceeding the Supply Voltage RAIL-TO-RAIL OUTPUT The approximate output resistance of the LMC7101 is 180 sourcing and 130 sinking at VS = 3V and 110 sourcing and 80 sinking at VS = 5V. Using the calculated output resistance, maximum output voltage swing can be estimated as a function of load. CAPACITIVE LOAD TOLERANCE The LMC7101 can typically directly drive a 100 pF load with VS = 15V at unity gain without oscillating. The unity gain follower is the most sensitive configuration. Direct capacitive loading reduces the phase margin of op amps. The combination of the op amp's output impedance and the capacitive load induces phase lag. This results in either an underdamped pulse response or oscillation. Capacitive load compensation can be accomplished using resistive isolation as shown in Figure 65. This simple technique is useful for isolating the capacitive input of multiplexers and A/D converters.

Resistive Isolation of a 330 pF Capacitive Load COMPENSATING FOR INPUT CAPACITANCE WHEN USING LARGE VALUE FEEDBACK RESISTORS When using very large value feedback resistors, (usually > 500 k) the large feed back resistance can react with the input capacitance due to transducers, photo diodes, and circuit board parasitics to reduce phase margins. The effect of input capacitance can be compensated for by adding a feedback capacitor. The feedback capacitor (as in Figure 66), Cf is first estimated by: (1) or R1 CIN R2 Cf (2) which typically provides significant overcompensation. Printed circuit board stray capacitance may be larger or smaller than that of a breadboard, so the actual optimum value for CF may be different. The values of CF should be checked on the actual circuit. (Refer to the LMC660 quad CMOS amplifier data sheet for a more detailed discussion.) Figure 66.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
