LM2902W
LM2902W is Low-power quad operational amplifier manufactured by STMicroelectronics.
Features
- Wide gain bandwidth: 1.3 MHz
- Input mon-mode voltage range includes negative rail
- Large voltage gain: 100 d B
- Very low supply current per amplifier: 375 µA
- Low input bias current: 20 n A
- Low input offset current: 2 n A
- ESD internal protection: 800 V
- Wide power supply range
- Single supply: 3 V to 30 V
- Dual supplies: ±1.5 V to ±15 V
Description
This circuit consists of four independent, high-gain operational amplifiers which have frequency pensation 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.
