Resistive Sensor Signal Conditioner with Digital Output

The ZSC31014 RBiciLite™ is a feature rich CMOS integrated circuit for high accuracy amplification and analog-to-digital conversion of a differential input signal. Perfect for low-cost applications, the ZSC31014 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, the ZSC31014 can also provide a corrected temperature output through an internal or external sensor measurement. Digital compensation of signal offset, sensitivity, temperature and non-linearity is accomplished via an internal digital signal processor running a correction algorithm. Calibration coefficients are stored in a highly reliable non-volatile EEPROM. Measured and corrected bridge values provided at the digital output pins can easily be configured as I2C or SPI. Programming of the ZSC31014 is made simple by the I2C interface and the PC-controlled calibration software provided in the IDT Evaluation Kit. Digital mating of the sensor with the signal conditioner is fast and precise, eliminating the overhead normally associated with trimming external components and multi-pass calibration routines.

Integrated diagnostics functions and low power stand-by-mode make the ZSC31014 attractive for a variety of battery-operated applications, particularly products involving the use of a microcontroller for networking sensors.


  • Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity
  • Eight programmable analog gain and digital gain settings; accommodates bridges with spans < 1mV/V and high offset
  • Internal or optional external temperature compensation for sensor correction and for corrected temperature out
  • Diagnostic features (e.g., EEPROM signature, bridge connection checks, bridge short detection)
  • 32-bit customer ID field for module traceability
  • Digital single-pass calibration via I2C
  • Fast power-up to data output response: 3ms
  • Current consumption depends on programmed sample rate: as low as 200
