High End 24-Bit Sensor Signal

Conditioner IC

ZSSC3224

Datasheet

Brief Description

Benefits

The ZSSC3224 is a sensor signal conditioner (SSC) IC

for high-accuracy amplification and analog-to-digital con-

version of a differential or pseudo-differential input

signal. Designed for high-resolution sensor module

applications, the ZSSC3224 can perform offset, span,

and 1^stand 2^ndorder 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.



Integrated 26-bit calibration math digital signal

processor (DSP)



Fully corrected signal at digital output

Layout customized for die-die bonding with sensor for

high-density chip-on-board assembly



One-pass calibration minimizes calibration costs

No external trimming, filter, or buffering components

required



Highly integrated CMOS design

Integrated reprogrammable non-volatile memory

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

Excellent for low-voltage and low-power battery

applications



Optimized for operation in calibrated resistive

(e.g., pressure) sensor or calibrated absolute voltage

(e.g., thermopile) sensor modules

accomplished via

processor (DSP) running

26-bit internal digital signal

correction algorithm.

Calibration coefficients are stored on-chip in a highly

reliable, non-volatile, 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.
