Automotive Sensor Signal Conditioner for Ceramic Sensor Applications

The ZSSC3138 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 ZSSC3138 offers a maximum analog gain of 420 and two offset compensation features. These fit the requirements of ceramic thick-film-based sensor elements as well as strain gauges perfectly. The high amplification in combination with the offset compensation offers the capability to set up ceramic-thick-film-based sensor applications without laser trimming, which leads to better long-term stability.
