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.

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
