Abstract
An ASIC for current, voltage and temperature measurements has signal inputs (RSHH, VBAT, ETS, ETR) for receiving input signals, several choppers, an amplifier, an analog/digital converter and a digital signal output for outputting the result of the measurement and for communicating with a higher-order control unit. The invention proposes that the measuring circuit contain several differential signal inputs (RSHH-RSHL, VBAT-RSHL, ETS-RSHL, ETR-RSHL and VBAT-ETS), wherein one respective chopper/multiplexer is arranged downstream of each signal input.
