General Description

The ZSSC3241 is a sensor signal conditioning IC (SSC) for highly accurate amplification, digitization, and sensor-specific correction of resistive sensor signals.

The ZSSC3241 provides best-in-class sensor-element adaptability, and it is suitable for bridge and half-bridge sensors, as well as external voltage-source element and single-element sensors (e.g., Pt100 and external temperature sensor diodes) powered by an on-chip current source.

Digital compensation of the sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via a 26-bit math core running a correction algorithm with calibration coefficients stored in a non-volatile, reprogrammable memory.

Overview

ZSSC3241 Sensor Signal Conditioner IC for Resistive Sensors Datasheet.

Key Features

  • Digital communication and calibration interfaces o SPI up to 10MHz o I2C (Standard, Fast, and High-Speed Mode) o One-wire-interface (OWI), up to 100kBit/s.
  • Accommodates nearly all resistive bridge sensor types (signal spans from 1mV/V up to 500mV/V).
  • Supports different sensor element configurations: o Resistive bridge or half-bridge o Resistive divider string o Voltage source.
  • On-chip temperature sensor.
  • External temperature sensing supported, e. g. s.
