Brief Description
ZMD31050 is a CMOS integrated circuit for highlyaccurate amplification and sensor-specific correction of bridge sensor signals. The device provides digital compensation of sensor offset, sensitivity, temperature drift and non-linearity by a 16-bit RISC micro controller running a correction algorithm with correction coefficients stored in non-volatile EEPROM.

FEATUREs
• Digital compensation of sensor offset, sensitivity,
  temperature drift and non-linearity
• Accommodates nearly all bridge sensors types
  (signal spans from 1 up to 275mV/V processable)
• Digital one-shot calibration: quick and precise
• Selectable temperature compensation reference:
  bridge, thermistor, internal diode or external diode
• Output options: voltage (0...5V), current
  (4...20mA), PWM, I2C, SPI, ZACwireTM (onewire-interface), alarm
• Adjustable output resolution (up to 15 bits) versus
  sampling rate (up to 3.9kHz)
• Selectable bridge excitation: ratiometric voltage,
  constant voltage or constant current
• Input channel for separate temperature sensor
• Sensor connection and common mode check
  (Sensor aging detection)
• operation temperature, depending on product
  version, up to -40...+125°C (-55...+150°C
  derated)
• Supply voltage +2.7V...+5.5V
• Available in SSOP16 or as die
