Product data

AU2902

DESCRIPTION

The AU2902 consists of four independent, high-gain, internally

frequency-compensated operational amplifiers designed specifically

to operate from a single power supply over a wide range of voltages.

UNIQUE FEATURES

In the linear mode, the input common-mode voltage range includes

ground and the output voltage can also swing to ground, even

though operated from only a single power supply voltage.

The unity gain crossover frequency and the input bias current are

temperature-compensated.

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: 3 VDC to 30 VDC or dual

supplies: ±1.5 VDC to ±15 VDC

• Very low supply current drain: essentially independent of supply

voltage (1 mW/op amp at +5 VDC)

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

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

• Differential input voltage range equal to the power supply voltage

• Large output voltage: 0 VDC to VCC – 1.5 VDC swing
