LM2902W
Low-power quad operational amplifier
Datasheet - production data
Description
This circuit consists of four independent, highgain operational amplifiers which have frequency
compensation implemented internally and are
designed especially for automotive and industrial
control systems.
The device operates from a single power supply
over a wide range of voltages. Operation from
split power supplies is also possible and the low
power supply current drain is independent of the
magnitude of the power supply voltage.
All the pins are protected against electrostatic
discharges up to 800 V.
Features
Wide gain bandwidth: 1.3 MHz
Input common-mode voltage range includes
negative rail
Large voltage gain: 100 dB
Very low supply current per amplifier:
375 µA
Low input bias current: 20 nA
Low input offset current: 2 nA
ESD internal protection: 800 V
Wide power supply range
Single supply: 3 V to 30 V
Dual supplies: ±1.5 V to ±15 V

Notes:
(1)
+
Short-circuits from the output to VCC can cause excessive heating and potential destruction. The maximum
+
output current is approximately 20 mA, independent of the magnitude of VCC
(2)
This input current only exists when the voltage at any of the input leads is driven negative. It is due to the
collector-base junction of the input PNP transistor becoming forward biased and thereby acting as an input diode
clamp. In addition to this diode action, there is also NPN parasitic action on the IC chip. This transistor action can
cause the output voltages of the op amps to go to the VCC voltage level (or to ground for a large overdrive) for the
time during which an input is driven negative. This is not destructive and normal output is restored for input
voltages higher than -0.3 V.
(3)
Rthja/c are typical values.
(4)
Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ
resistor between two pins of the device. This is done for all couples of connected pin combinations while the other
pins are floating.
(5)
Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected
pin combinations while the other pins are floating.
(6)
Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

(2)
The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output, so
there is no change in the load on the input lines.
(3)
Due to the proximity of external components, ensure that stray capacitance does not cause coupling between these external
parts. Typically, this can be detected as this type of capacitance increases at higher frequencies.

Macromodel
Macromodel
An accurate macromodel of the LM2902W is available on STMicroelectronics’ web site at
www.st.com. This model is a trade-off between accuracy and complexity (that is, time
simulation) of the LM2902W operational amplifiers. It emulates the nominal performances
of a typical device within the specified operating conditions mentioned in the datasheet. It
also helps to validate a design approach and to select the right operational amplifier, but it
does not replace on-board measurements.
