LM2902W is a low-power quad operational amplifier launched by ST, which has wide bandwidth gain, input common-mode voltage range includes negative rail, large voltage gain, low supply current, low input bias current, low input offset current, ESD internal protection, wide power supply range, single supply, dual supplies.
The LM2902W is a low-power quad operational amplifier designed for automotive and industrial control systems. It consists of four independent, high-gain, internally frequency-compensated amplifiers that operate from a single power supply over a wide range of voltages or split power supplies. All pins are protected against electrostatic discharges up to 800 V.
Key features include a wide gain bandwidth of 1.3 MHz, a large voltage gain of 100 dB, and very low supply current per amplifier of 375 µA. The device supports a single supply voltage range of +3 V to +30 V and dual supplies of ±1.5 V to ±15 V. It also features a low input bias current of 20 nA and low input offset current of 2 nA.
