IDT – Sensor signal conditioner with on-board DSP performs compensation and correction


The ZSSC3018 from IDT is a sensor signal conditioner IC which provides accurate amplification and digitisation of differential or pseudo-differential input signals.

Intended for use in circuits containing a high-resolution sensor module, the ZSSC3018 can perform offset, span, and first- and second-order temperature compensation of the measured signal. Corrected sensor values are provided at the digital output pins, which can be configured as an I2C or serial peripheral interface.

Digital compensation of signal offset, sensitivity, temperature and non-linearity is accomplished via an internal DSP running a correction algorithm. Calibration coefficients are stored on-chip in non-volatile memory.
