ZSSC3018BA3W

ZSSC3018 is a versatile, high-resolution 18bit sensor signal conditioner integrated circuit for high-accuracy amplification and analogy-to-digital conversion of differential or pseudo-differential input signals. It is designed for high-resolution sensor module applications, this can perform offset, span and 1st and 2nd order temperature compensation of the measured signal. It is developed for the correction of resistive bridge or absolute voltage sensors, it can also provide a corrected temperature output measured with an internal sensor. The measured and corrected sensor values are provided at the digital output pins, which can be configured as I²C (≤ 3.4MHz) or SPI (≤ 10MHz). The digital compensation of signal offset, sensitivity, temperature and non-linearity is accomplished via a 26bit internal digital signal processor (DSP) running a correction algorithm. The calibration coefficients are stored onchip in a highly reliable, non-volatile, multiple-time programmable (MTP) memory.
