Brief Description
The ZSC31150 is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via an internal 16-bit RISC microcontroller running a correction algorithm, with calibration coefficients stored in an EEPROM.

FEATUREs
◾ Digital compensation of sensor offset, sensitivity,
   temperature drift, and non-linearity
◾ Adjustable to nearly all bridge sensor types
◾ Analog gain of up to 420
◾ Output options: ratiometric analog voltage output (5% to 95%
   maximum, 12.4-bit resolution) or ZACwire™ (digital one-wireinterface)
◾ Temperature compensation: internal or external diode, bridge
   resistance, thermistor
◾ Sensor biasing by voltage or constant current
◾ Sample rate: up to 7.8kHz
◾ High voltage protection up to 33V
◾ Supply current: max. 5.5mA
◾ Reverse polarity and short-circuit protection
◾ Wide operation temperature depending on part number: up to
   -40°C to +150°C
◾ Traceability by user-defined EEPROM entries
◾ Safety and diagnostic functions

Benefits
◾ No external trimming components required
◾ Only a few external protection devices needed
◾ PC-controlled configuration and single pass calibration via
   I2C or ZACwire™ interface: simple, cost efficient, quick, and
   precise
◾ End-of-line calibration via I2C or ZACwire™ interface
◾ High accuracy (0.25% FSO at -25 to 85°C; 0.5% FSO
   at -40°C to 125°C)
◾ Excellent EMC/ESD robustness and AEC-Q100 qualification
