DESCRIPTION

The AU2904 consists of two independent, high-gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage.

FEATURES

• Internally frequency-compensated for unity gain

• Large DC voltage gain: 100dB

• Wide bandwidth (unity gain): 1MHz (temperature-compensated)

• Wide power supply range Single supply: 3VDC to 30VDC or dual supplies: ±1.5VDC to ±15VDC

• Very low supply current drain (400µA): essentially independent of supply voltage (1mW/op amp at +5VDC)

• Low input bias current: 45nADC (temperature-compensated)

• Low input offset voltage: 2mVDC and offset current: 5nADC

• Differential input voltage range equal to the power supply voltage

• Large output voltage: 0VDC to V+-1.5VDC swing
