Overview
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 current: Max.
5.
5mA • Reverse polarity and short circuit protection • Wide operation temperature range: -40 to +150°C • Traceability by user-defined EEPROM entries * Note: I2C™ is a trademark of NXP.
** FSO = Full Scale Output.
Benefits • Family approach offers the best fitting IC selection to build cost-optimized applications • No external trimming components required • Low number of external components needed • PC-controlled configuration and One-Pass/ endof-line calibration via I²C™* or ZAC...
