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
S
and a maximum differential input voltage of V
S
. The IC is
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.
