Overview
Sensor Signal Conditioner for Piezoresistive Bridge Sensors ZSSC3135 Datasheet Brief Description The ZSSC3135 is a member of the ZSSC313x 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 ZSSC3135 is specially designed for piezoresistive bridge sensor elements.
The amplification stage with an analog gain of 105 in combination with optional temperature compensation via an external temperature sensor meets or exceeds the requirements of piezoresistive sensor applications.
Features • Adjustable to nearly all resistive bridge sensor types: analog gain of up to 105, maximum overall gain of 420 • Sample rate up to 200 Hz • ADC resolution 13/14 bit • Safety functionality sensor connection • External temperature sensor • 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 ZACwire™ (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/ end-of-line calibration via I²C™* or ZACwir...
