LM2902

SO14 TSSOP14 QFN16 3x3 wettable flank LM2902 Datasheet Low-power quad operational amplifiers Features Wide gain bandwidth: 1.3 MHz Input common-mode voltage range includes negative rail Large voltage gain: 100 dB Supply current per amplifier: 375 µA Low input bias current: 20 nA Low input offset current: 2 nA 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 (op amps) which employ internal frequency compensation and are specifically designed 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 from the power supply voltage magnitude.
