The ZSSC3135 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 nonlinearity of the connected sensor element. The required calibration coefficients are stored by the single-pass calibration procedure in an on-chip EEPROM. The ZSSC3135 is specially designed for piezo-resistive bridge sensor elements. The amplification stage with an analog gain of 105 in combination with the optional temperature compensation using an external temperature sensor fits the requirements of piezo-resistive sensor applications perfectly.
