Output Operational Amplifiers

General Description

The LPV321/358/324 are low power (9 µA per channel at

5.0V) versions of the LMV321/358/324 op amps. This is

another addition to the LMV321/358/324 family of commod-

ity op amps.

The LPV321/358/324 are the most cost effective solutions

for the applications where low voltage, low power operation,

space saving and low price are needed. The LPV321/358/

324 have rail-to-rail output swing capability and the input

common-mode voltage range includes ground. They all ex-

hibit excellent speed-power ratio, achieving 5 kHz of band-

width with a supply current of only 9 µA.

The LPV321 is available in space saving 5-Pin SC70, which

is approximately half the size of 5-Pin SOT23. The small

package saves space on PC boards, and enables the design

of small portable electronic devices. It also allows the de-

signer to place the device closer to the signal source to

reduce noise pickup and increase signal integrity.

The chips are built with National’s advanced submicron

silicon-gate BiCMOS process. The LPV321/358/324 have

bipolar input and output stages for improved noise perfor-

mance and higher output current drive.

Application Information

BENEFITS OF THE LPV321/358/324

Size

The small footprints of the LPV321/358/324 packages save

space on printed circuit boards, and enable the design of

smaller electronic products, such as cellular phones, pagers,

or other portable systems. The low profile of the LPV321/

358/324 make them possible to use 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 LPV321/358/324 can be placed closer to the signal

source, reducing noise pickup and increasing signal integrity.

Simplified Board Layout

These products help you to avoid using long pc traces in

your pc board layout. This means that no additional compo-

nents, such as capacitors and resistors, are needed to filter

out the unwanted signals due to the interference between

the long pc traces.

Low Supply Current

These devices will help you to maximize battery life. They

are ideal for battery powered systems.

Low Supply Voltage

National provides guaranteed performance at 2.7V and 5V.

These guarantees ensure operation throughout the battery

lifetime.

Rail-to-Rail Output

Rail-to-rail output swing provides maximum possible dy-

namic range at the output. This is particularly important

when operating on low supply voltages.

Input Includes Ground

Allows direct sensing near GND in single supply operation.

The differential input voltage may be larger than V

without

damaging the device. Protection should be provided to pre-

vent the input voltages from going negative more than −0.3V

(at 25˚C). An input clamp diode with a resistor to the IC input

terminal can be used.

CAPACITIVE LOAD TOLERANCE

The LPV321/358/324 can directly drive 200 pF in unity-gain

without oscillation. The unity-gain follower is the most sensi-

tive configuration to capacitive loading. Direct capacitive

loading reduces the phase margin of amplifiers. The combi-

nation of the amplifier’s output impedance and the capacitive

load induces phase lag. This results in either an under-

damped pulse response or oscillation. To drive a heavier

capacitive load, circuit in Figure 1 can be used.

In Figure 1, the isolation resistor R

ISO

and the load capacitor

form a pole to increase stability by adding more phase

margin to the overall system. The desired performance de-

pends on the value of R

ISO

. The bigger the R

ISO

resistor

value, the more stable V

OUT

will be. Figure 2 is an output

waveform of Figure 1 using 100 kΩfor R

ISO

and 1000 pF for

The circuit in Figure 3 is an improvement to the one in Figure

1because it provides DC accuracy as well as AC stability. If

there were a load resistor in Figure 1, the output would be

voltage divided by R

ISO

and the load resistor. Instead, in

Figure 3,R

provides the DC accuracy by using feed-

forward techniques to connect V

to R

. Caution is needed

in choosing the value of R

due to the input bias current of

the LPV321/358/324. C

and R

ISO

serve to counteract the

loss of phase margin by feeding the high frequency compo-

nent of the output signal back to the amplifier’s inverting

input, thereby preserving phase margin in the overall feed-

back loop. Increased capacitive drive is possible by increas-

ing the value of C

. This in turn will slow down the pulse

response.

Application Information (Continued)

INPUT BIAS CURRENT CANCELLATION

The LPV321/358/324 family has a bipolar input stage. The

typical input bias current of LPV321/358/324 is 1.5 nA with

5V supply. Thus a 100 kΩinput resistor will cause 0.15 mV

of error voltage. By balancing the resistor values at both

inverting and non-inverting inputs, the error caused by the

amplifier’s input bias current will be reduced. The circuit in

Figure 4 shows how to cancel the error caused by input bias

current.

TYPICAL SINGLE-SUPPLY APPLICATION CIRCUITS

Difference Amplifier

The difference amplifier allows the subtraction of two volt-

ages or, as a special case, the cancellation of a signal

common to two inputs. It is useful as a computational ampli-

fier, in making a differential to single-ended conversion or in

rejecting a common mode signal.

Instrumentation Circuits

The input impedance of the previous difference amplifier is

set by the resistor R

, and R

. To eliminate the

problems of low input impedance, one way is to use a

voltage follower ahead of each input as shown in the follow-

ing two instrumentation amplifiers.

Three-op-amp Instrumentation Amplifier

The quad LPV324 can be used to build a three-op-amp

instrumentation amplifier as shown in Figure 6

The first stage of this instrumentation amplifier is a

differential-input, differential-output amplifier, with two volt-

age followers. These two voltage followers assure that the

input impedance is over 100 MΩ. The gain of this instrumen-

tation amplifier is set by the ratio of R

should equal

and R

equal R

. Matching of R

to R

and R

to R

affects the CMRR. For good CMRR over temperature, low

drift resistors should be used. Making R

Slightly smaller

than R

and adding a trim pot equal to twice the difference

between R

and R

will allow the CMRR to be adjusted for

optimum.

Application Information (Continued)

Two-op-amp Instrumentation Amplifier

A two-op-amp instrumentation amplifier can also be used to

make a high-input-impedance DC differential amplifier (Fig-

ure 7). As in the three-op-amp circuit, this instrumentation

amplifier requires precise resistor matching for good CMRR.

should equal to R

and R

should equal R

Single-Supply Inverting Amplifier

There may be cases where the input signal going into the

amplifier is negative. Because the amplifier is operating in

single supply voltage, a voltage divider using R

and R

implemented to bias the amplifier so the input signal is within

the input common-common voltage range of the amplifier.

The capacitor C

is placed between the inverting input and

resistor R

to block the DC signal going into the AC signal

source, V

. The values of R

and C

affect the cutoff fre-

quency, fc = 1/2πR

As a result, the output signal is centered around mid-supply

(if the voltage divider provides V

/2 at the non-inverting

input). The output can swing to both rails, maximizing the

signal-to-noise ratio in a low voltage system.

ACTIVE FILTER

Simple Low-Pass Active Filter

The simple low-pass filter is shown in Figure 9. Its low-

frequency gain(ω→o) is defined by −R

. This allows

low-frequency gains other than unity to be obtained. The

filter has a −20 dB/decade roll-off after its corner frequency

fc. R

should be chosen equal to the parallel combination of

and R

to minimize errors due to bais current. The

frequency response of the filter is shown in Figure 10

Note that the single-op-amp active filters are used in to the

applications that require low quality factor, Q (≤10), low

frequency (≤5 kHz), and low gain (≤10), or a small value for

the product of gain times Q (≤100). The op amp should have

an open loop voltage gain at the highest frequency of inter-

est at least 50 times larger than the gain of the filter at this

frequency. In addition, the selected op amp should have a

slew rate that meets the following requirement:

Slew Rate ≥0.5x(ω

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,

and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are

sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard

warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where

mandated by government requirements, testing of all parameters of each product is not necessarily performed.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and

applications using TI components. To minimize the risks associated with customer products and applications, customers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,

or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information

published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a

warranty or endorsement thereof. Use of such information 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.

Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied

by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive

business practice. TI is not responsible or liable for such altered 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.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably

be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing

such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and

acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products

and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in

such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are

specifically designated by TI as military-grade or "enhanced plastic."Only products designated by TI as military-grade meet military

specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are

designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated

products in automotive applications, TI will not be responsible for any failure to meet such requirements.
