ZSSC3131

Sensor Signal Conditioner for Cost Optimized Switch Applications

The ZSSC3131 is a member of the ZSSC313x product family of CMOS integrated circuits designed for automotive and industrial sensor applications. All family members are well suited for highly accurate amplification and sensor-specific correction of resistive bridge sensor signals. An internal 16-bit RISC microcontroller running a correction algorithm compensates sensor offset, sensitivity, temperature drift, and non-linearity of the connected sensor element. The required calibration coefficients are stored by the single-pass calibration procedure in an on-chip EEPROM. The ZSSC3131 is optimized for simple switch and cost-sensitive sensor applications. The integrated adjustable digital filter offers the possibility to setup fast switching real-time applications as well as stabilized applications in the event of disturbed or unstable switching input signals.
