ZSC31014EIG1-T

ZSC31014EIG1-T is a RBicilite™ digital output sensor signal conditioner in a 8 pin SOP package. The ZSC31014 is a CMOS integrated circuit for highly accurate amplification and analogue-to-digital conversion of differential and half-bridge input signals. It can compensate the measured signal for offset, 1st and 2nd order span, and 1st and 2nd order temperature. 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. It is adjustable to nearly all piezoresistive bridge sensors. Measured and corrected bridge values are provided at digital output pins, which can be configured as I2C or SPI. The digital I2C interface can be used for a simple PC controlled calibration procedure to program calibration coefficients into an on-chip EEPROM.
