Brief Description
The ZSSC3026 is a sensor signal conditioner (SSC) integrated circuit for high-accuracy amplification and analog-to-digital conversion of a differential input signal. Developed for correction of resistive bridge sensors and optimized for high-resolution altimeter module applications, the ZSSC3026 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. It can also provide a corrected temperature output measured with an internal sensor. The corrected measurement values are provided at the digital output pins, which can be configured as I2C™* (≤3.4MHz) or SPI (≤20MHz).
