ZSSC3224 High End 24-Bit Sensor Signal Conditioner IC

2020-04-30
The ZSSC3224 is a sensor signal conditioner (SSC) IC for highaccuracy amplification and analog-to-digital conversion of a differential or pseudo-differential input signal. Designed for high resolution sensor module applications, the ZSSC3224 can perform offset,

span, and 1st and 2nd order temperature compensation of the

measured signal. Developed for 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 (≤20MHz). Digital compensation of signal offset, sensitivity,

temperature, and non-linearity is accomplished via a 26-bit internal

digital signal processor (DSP) running a correction algorithm.

Calibration coefficients are stored on-chip in a highly reliable, nonvolatile, multiple-time programmable (MTP) memory. Programming

the ZSSC3224 is simple via the serial interface. The interface is

used for the PC-controlled calibration procedure, which programs

the set of calibration coefficients in memory. The ZSSC3224

provides accelerated signal processing, increased resolution, and

improved noise immunity in order to support high-speed control,

safety, and real-time sensing applications with the highest

requirements for energy efficiency.
