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 in an on-chip EEPROM.
The ZSSC3138 offers a maximum analog gain of 420 and two offset compensation features. These fit perfectly to the requirements of ceramic thick-film based sensor elements as well as strain gauges. The high amplification in combination with the offset compensation offers the capability to set up ceramic thick-film sensor applications without laser trimming, which leads to better long-term stability.
Support includes evaluation kits, application notes and mass calibration system.
Optimized for ceramic sensor and strain gauge applications.
