Brief Description
ZMD31030 is a CMOS integrated circuit for highly-accurate amplification and sensor-specific correction of bridge sensor and temperature sensor signals.
Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity is accomplished via a 16-bit RISC microcontroller running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM.
The ZMD31030 is adjustable to nearly all piezo-resistive bridge sensors. Measured values are provided at the PWM output or at the LIN interface.

FEATUREs
• Digital compensation of sensor offset, sensitivity,
   temperature drift and non-linearity
• Adjustable to nearly all piezo-resistive bridge sensor types
• Digital one-shot calibration: quick and precise
• Selectable temperature compensation reference:
   internal or external diode
• Selectable separate input channel for an external
   temperature sensor
• Output options: PWM (bridge sensor signal)
   or LIN interface (bridge and temp. sensor signal)
• Digital sensor calibration via LIN interface
• Sampling rate typically 125Hz
• High voltage protection
• Reverse polarity and short circuit protection
• Operation temperature -40 to +125°C
• Supply voltage 8 to 18V
