ZSC31150
Fast Automotive Sensor Signal Conditioner
Brief Description
Benefits
The ZSC31150 is a CMOS integrated circuit for
highly accurate amplification and sensor-specific
correction of bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperature
drift, and non-linearity is accomplished via an internal 16-bit RISC microcontroller running a correction
algorithm, with calibration coefficients stored in an
EEPROM.

The ZSC31150 is adjustable to nearly all bridge sensor types. Measured values are provided at the
analog voltage output or at the digital ZACwire™
and I²C™* interface. The digital interface can 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
with trimming by external devices or a laser.
