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.

■ Wide gain bandwidth: 1.3MHz
■ Input common-mode voltage range includes ground
■ Large voltage gain: 100dB
■ Very low supply current/ampli: 375µA
■ Low input bias current: 20nA
■ Low input offset voltage: 5mV max.
   (for more accurate applications, use the
   equivalent parts LM124A-LM224A-LM324A
   which feature 3mV max.)
■ Low input offset current: 2nA
■ Wide power supply range:
   Single supply: +3V to +30V
   Dual supplies: ±1.5V to ±15V
