LM2902/ LM2902A/ LM2904/ LM2904A

DUAL AND QUAD OPERATIONAL AMPLIFIERS

Description

The LM2902/2904 series amplifiers consist of four and two

independent high-gain operational amplifiers with very low input offset

voltage specification. They have been designed to operate from a

single power supply over a wide range of voltages; however operation

from split power supplies is also possible. They offer low power

supply current independent of the magnitude of the power supply

voltage.

The LM2902/2904 series are characterized for operation from

-40℃ to +125℃ and the dual devices are available in SO-8 and the

quad devices available in SO-14 and TSSOP-14 with industry

standard pin-outs. Both use green mold compound as standard.

 Single supply: 3V to 36V

 Dual supplies: ±1.5V to ±18V

 Very low supply current drain

 Non-A Version…2mV(Typ.)

 Large DC voltage gain: 100dB

 Wide bandwidth (unity gain): 700KHz (temperature

compensated)

 Internally compensated with unity gain.

 Input common-mode voltage range includes ground

 Differential input voltage range equal to the power supply voltage

 Large output voltage swing: 0V to V

 SO-8(duals) and SO-14/TSSOP-14(quads) packages available

 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

 Halogen and Antimony Free. “Green” Device (Note 3)

Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.

Application Information

General Information

The LM2902/2904 series are op amps which operate with only a single power supply voltage, have true-differential inputs, and remain in the linear

mode with an input common-mode voltage of 0 V

performance characteristics. At +25°C amplifier operation is possible down to a minimum supply voltage of 2.3 V

Precautions should be taken to insure that the power supply for the integrated circuit never becomes reversed in polarity or that the unit is not

inadvertently installed backwards in a test socket as an unlimited current surge through the resulting forward diode within the IC could cause fusing

of the internal conductors and result in a destroyed unit.

Large differential input voltages can be easily accommodated and, as input differential voltage protection diodes are not needed, no large input

currents result from large differential input voltages. The differential input voltage may be larger than V

should be provided to prevent the input voltages from going negative more than -0.3 V

input terminal can be used.

To reduce the power supply current drain, the amplifiers have a class A output stage for small signal levels which converts to class B in a large

signal mode. These allows the amplifiers to both source and sink large output currents. Therefore both NPN and PNP external current boost

transistors can be used to extend the power capability of the basic amplifiers. The output voltage needs to raise approximately 1 diode drop above

ground to bias the on-chip vertical PNP transistor for output current sinking applications.

For ac applications, where the load is capacitive coupled to the output of the amplifier, a resistor should be used, from the output of the amplifier to

ground to increase the class A bias current and prevent crossover distortion. Where the load is directly coupled, as in dc applications, there is no

crossover distortion.

Capacitive loads which are applied directly to the output of the amplifier reduce the loop stability margin. Values of 50pF can be accommodated

using the worst-case non-inverting unity gain connection. Large closed loop gains or resistive isolation should be used if larger load capacitance

must be driven by the amplifier.

The bias network of the LM2902/2904 series establishes a quiescent current which is independent of the magnitude of the power supply voltage

over the range of 3 V

Output short circuits either to ground or to the positive power supply should be of short time duration. Units can be destroyed, not as a result of the

short circuit current causing metal fusing, but rather due to the large increase in IC chip dissipation which will cause eventual failure due to

excessive function temperatures. Putting direct short-circuits on more than one amplifier at a time will increase the total IC power dissipation to

destructive levels, if not properly protected with external dissipation limiting resistors in series with the output leads of the amplifiers. The larger

value of output source current which is available at +25°C provides a larger output current capability at elevated temperatures (see typical

performance characteristics) than a standard IC op amp.

The circuits presented in the section on typical applications emphasize operation on only a single power supply voltage. If complementary power

supplies are available, all of the standard op amp circuits can be used. In general, introducing a pseudo-ground (a bias voltage reference of V

will allow operation above and below this value in single power supply systems. Many application circuits are shown which take advantage of the

wide input common-mode voltage range which includes ground. In most cases, input biasing is not required and input voltages which range to

ground can easily be accommodated.

Power Supply Bypassing and Layout

The LM29xx family operate both single supply voltage range 3 to 36V or dual supply voltage ±1.5V to ±18V.

As with any operation amplifier, proper supply bypassing is critical for low noise performance and high power supply rejection. For single supply

operation system, a min. 0.1µF bypass capacitor should be recommended to place as close as possible between V

supply operation, both the positive supply pin and negative supply pin should be bypassed to ground with a separate 0.1µF ceramic capacitor.

2.2µF tantalum capacitor can be added for better performance. Keep the length of leads and traces that connect capacitors between LM29xx power

supply pin and ground as short as possible.
