ZSSC3218

High-End 18-Bit Sensor Signal

Conditioner

Datasheet

Brief Description

Benefits

•

Integrated 26-bit calibration math digital signal

processor (DSP)

The ZSSC3218 is a sensor signal conditioner (SSC)

integrated circuit for high-accuracy amplification and

analog-to-digital conversion of a differential or

pseudo-differential input signal. Designed for high-

resolution sensor module applications, the

ZSSC3218 can perform offset, span, and 1^stand 2^nd

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.

•

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 com-

ponents required

•

Highly integrated CMOS design

Integrated reprogrammable non-volatile memory

Excellent for low-voltage and low-power battery

applications

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, non-volatile,

multiple-time programmable (MTP) memory. Pro-

gramming the ZSSC3218 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 ZSSC3218

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.

•

Optimized for operation in calibrated resistive

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

voltage (e.g., thermopile) sensor modules
