Overview
Description
The ZSSC3281 is a dual path sensor signal conditioning IC (SSC) for highly accurate amplification, digitization, and sensor-specific correction of sensor signals. The ZSSC3281 is suitable for bridge and half-bridge sensors, as well as external voltage-source element and single-element sensors (for example, 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 32-bit ARM M3 based math core running a correction algorithm with calibration coefficients stored in a non-volatile, reprogrammable memory. The programmable, integrated sensor front-end allows optimally applying various sensors for a broad range of applications.
The ZSSC3281 provides measurement value readouts and programming capabilities via an I2C, SPI, or one-wire interface (OWI). Absolute and ratiometric voltage, current-loop, or interrupt outputs are supported by the ZSSC3281.
Features
- Digital communication and calibration interfaces:
- SPI up to 10MHz
- I2C (Standard, Fast, Fast+) and I3C SDR
- 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:
- Resistive bridge or half-bridge
- Resistive divider string
- Voltage source
- On-chip temperature sensor
- External temperature sensing supported, for example, sensor-bridge as temperature detector, external diode, etc.
- Programmable 16-bit digital-to-analog-converter and output (supporting “True-0Volt”-output):
- (0V to 1V) or (0V to 5V) absolute voltage output
- VDD-ratiometric voltage output
- 4mA to 20mA current-loop output supported
- 0V to 10V absolute-voltage output supported
- Wide operational temperature and supply range
- On-chip voltage regulators for sensor supply, and IC operation
- Support for extra regulation by external transistor, for example, JFET (especially for industrial supply voltages > 5.5VDC)
- Programmable sensor-signal-conditioning math core
- Reprogrammable, nonvolatile memory (NVM)
- On-chip diagnostics:
- Sensor connection
- AFE self-test
- Memory integrity
