Circuit Description

The IC contains two amplifiers with typical open-loop gain of 80 dB at 500 Hz.

The input stages consist of PNP-differential amplifiers. This produces a common-mode

input range of 0 V to nearly

V

guarded against ground shorts by an SOA-protective circuit. The output transistors are

turned off if the chip temperature exceeds approx. 160

°C. The IC can be turned off by

an inhibit input, which very much reduces current consumption.
