The ZSC31150 is a CMOS integrated circuit for amplification and sensor-specific correction of bridge sensor signals. The device provides digital compensation of sensor offset, sensitivity, temperature drift and non-linearity via a 16-bit RISC microcontroller running a correction algorithm. The ZSC31150 accommodates virtually any resistive bridge sensor (e.g., piezo-resistive and steel-membrane-based pressure sensors). The bi-directional digital interfaces (I2C and ZACwire™) can be used for a simple PC-controlled calibration procedure, encompassing writing and programming a set of calibration coefficients into an on-chip EEPROM. The ZSC31150 has been designed for automotive applications and is specifically suited for most pressure sensors. It can also be used with force, torque, acceleration, angle, position and revolution sensors. Safety applications (e.g. for braking or steering systems) are also supported by the ZSC31150's set of diagnostic functions. The ZSC31150 is optimized for automotive environments via protection circuitry and excellent electromagnetic compatibility.
