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 420, overall gain up to 2000
• Output options: ratiometric analog voltage
   output (5 - 95% in maximum, 12.4 bit
   resolution) or ZACwireTM (digital one-wireinterface)
• Temperature compensation: internal or external
   diode, bridge resistance, thermistor
• Sensor biasing by voltage or constant current
• Sample rate up to 7.8 kHz
• High voltage protection up to 33 V
• Supply current: max. 5.5mA
• Reverse polarity and short circuit protection
• Wide operation temperature up to -40…+150°C
• Traceability by user-defined EEPROM entries
• Several safety and diagnostic functions

Benefits
• No external trimming components required
• Only a few external protection devices needed
• PC-controlled configuration and One-Shot
   calibration via I²CTM or ZACwireTM interface:
   Simple, cost efficient, quick, and precise
• End-of-Line calibration via I²CTM or ZACwireTM
   interface
• High accuracy (0.25% FSO @ -25 to 85°C;
   0.5% FSO @ -40 to 125°C)
• The ZSC31150 is optimized for automotive
   environments by its special protection circuitry
   and excellent electromagnetic compatibility
