LM2902/LM2904
DUAL AND QUAD OPERATIONAL AMPLIFIERS
Description
The LM2902/LM2904 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/LM2904 series are characterized for operation from
-40℃ to +125℃ and the dual devices are available in SO-8, MSOP-8,
TSSOP-8 and the quad devices available in SO-14 and TSSOP-14
with industry standard pin-outs. Both use green mold compound as
standard.

Notes: 4. Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
5. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is
PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of +150°C can affect reliability.
6. Maximum power dissipation is a function of TJ(max), θJC, and TA. The maximum allowable power dissipation at any allowable ambient temperature is

7. Short circuits from outputs to VCC or ground can cause excessive heating and eventual destruction.

Notes: 9. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the
output so no loading change exists on the input lines.
10. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (@ +25°C). The upper end of the
common-mode voltage range is VCC -1.5V (@ +25°C), but either or both inputs can go to +36V without damage, independent of the magnitude of VCC.
11. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can
be detected as this type of capacitance increases at higher frequencies.
12. Typical values are all at TA = +25°C conditions and represent the most likely parametric norm as determined at the time of characterization. Actual
typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed
on shipped production material.
13. All limits are guaranteed by testing or statistical analysis. Limits over the full temperature are guaranteed by design, but not tested in production.

LM2902/LM2904
Application Information
General Information
The LM2902/LM2904 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 0VDC. These amplifiers operate over a wide range of power supply voltage with little change in
performance characteristics. At +25°C amplifier operation is possible down to a minimum supply voltage of 2.3VDC.
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+ without damaging the device. Protection
should be provided to prevent the input voltages from going negative more than -0.3VDC (@ +25°C). An input clamp diode with a resistor to the IC
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 allow 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/LM2904 series establishes a quiescent current which is independent of the magnitude of the power supply
voltage over the range of 3VDC to 30VDC.
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 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 VCC/2)
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.

LM2902/LM2904
Application Information (Cont.)
Power Supply Bypassing and Layout
The LM2902/LM2904 operate both single supply voltage range 3V 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 minimum 0.1µF bypass capacitor should be recommended to place as close as possible between the VCC Pin and GND. For
dual 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 the
LM2902/LM2904 power supply pin and ground as short as possible.
