ZSSC3138BA2T

ZSSC3138 is an automotive sensor signal conditioner for ceramic sensor applications. It is a member of the ZSSC313x product family of CMOS integrated circuits that is 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 16bit RISC microcontroller running a correction algorithm compensates for 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 onchip EEPROM. This offers a maximum analogy gain of 420 and two offset compensation features. This fit the requirements of ceramic thick-film-based sensor elements as well as strain gauges perfectly.
