Brief Description
The ZSSC3138 is a member of the ZSSC313x product family of CMOS integrated circuits designed for automotive/ 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 one-pass calibration procedure on chip (EEPROM).
