DESCRIPTION

The LM2904 consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to 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

• Internally frequency compensated for unity gain

• Large dc voltage gain: 100 dB

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

• Wide power supply range:

   — Single supply: 3V to 32V

   — or dual supplies: ±1.5V to ±16V

• Very low supply current drain (500 µA)—essentially independent of supply voltage.

• Low input offset voltage: 2 mV

• Input common-mode voltage range includes ground

• Differential input voltage range equal to the power supply voltage

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