ZSC31150 Fast Automotive Sensor Signal Conditioner Datasheet Brief Description Benefits The ZSC31150 is a CMOS integrated circuit for highly accurate No external trimming components required amplification and sensor-specific correction of bridge sensor Only a few external protection devices needed signals. Digital compensation of sensor offset, sensitivity, PC-controlled configuration and single pass calibration via temperature drift, and non-linearity is accomplished via an internal 2 I C or ZACwire interface: simple, cost efficient, quick, and 16-bit RISC microcontroller running a correction algorithm, with precise calibration coefficients stored in an EEPROM. 2 End-of-line calibration via I C or ZACwire interface The ZSC31150 is adjustable to nearly all bridge sensor types. High accuracy (0.25% FSO at -25 to 85C 0.5% FSO Measured values are provided at the analog voltage output or at at -40C to 125C) 2 the digital ZACwire and I C interface. The digital interface can Excellent EMC/ESD robustness and AEC-Q100 qualification be used for a simple PC-controlled calibration procedure in order to program a set of calibration coefficients into an on-chip EEPROM. A specific sensor and a ZSC31150 can be mated digitally: fast, precise, and without the cost overhead associated Available Support with trimming by external devices or a laser.
