DESCRIPTION

The 532/358/LM2904 consists of two independent, high gain,

internally frequency-compensated operational amplifiers 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.

UNIQUE FEATURES

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

ground and the output voltage can also swing to includes ground

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

operated from only a single power supply voltage. The unity gain

cross frequency is temperature-compensated. The input bias current

is also temperature-compensated.
