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.
