ZSSC3131
ZSSC3131 is Sensor Signal Conditioner manufactured by Renesas.
Sensor Signal Conditioner for Cost Optimized Switch Applications
Brief Description
The ZSSC3131 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 pensates 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 ZSSC3131 is optimized for simple switch and cost-sensitive sensor applications. The integrated adjustable digital filter enables building fast-switching real-time applications as well as stabilized applications for switching input signals that are unstable or disrupted.
