LM2902W Low-power quad operational amplifier Datasheet - production data Description This circuit consists of four independent, high- gain 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 February 2016 DocID9922 Rev 10 1/19 This is information on a product in full production. www.st.com

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. DocID9922 Rev 10 7/19

LM2902W Macromodel 7 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. DocID9922 Rev 10 13/19
