Description
These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers. They operate 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.

Features
■ Wide gain bandwidth: 1.3 MHz
■ Input common-mode voltage range includes ground
■ Large voltage gain: 100 dB
■ Very low supply current/amplifier: 375 µA
■ Low input bias current: 20 nA
■ Low input offset voltage: 3 mV max.
■ 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
