ZSC31014EAG1

The ZSC31014EAG1 is a CMOS Signal Conditioner for highly accurate amplification and analog-to-digital conversion of differential and half-bridge input signals. The RBiciLite™ can compensate the measured signal for offset, 1st and 2nd order span and 1st and 2nd order temperature (Tco and Tcg). It is well-suited for sensor-specific correction of bridge sensors. Digital compensation of signal offset, sensitivity, temperature drift and non-linearity is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM. The RBiciLite™ is adjustable to nearly all piezo-resistive bridge sensors. Measured and corrected bridge values are provided at digital output pins, which can be configured as I²C™* or SPI. The digital I²C inter-face can be used for a simple PC-controlled calibration procedure to program calibration coefficients into an on-chip EEPROM.
