ZSSC3131

Sensor Signal Conditioner for CostOptimized Switch Applications ZSSC3131 Datasheet 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 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 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. Features Adjustable to nearly all resistive bridge sensor types: maximum analog gain of 105; maximum overall gain of 420 Sample rate up to 200 Hz ADC resolution 13/14 bit Internal temperature compensation Integrated adjustable digital filter Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity Output options: ratiometric analog voltage output (5 - 95% maximum, 12.4 bit resolution) or ZACwireTM (digital One-Wire Interface (OWI)) Sensor biasing by voltage High voltage protection up to 33 V Supply...
