Overview

Description

The ZSSC3015 RBicdLite-Auto™ sensor signal conditioner IC is adjustable to nearly all piezo-resistive bridge sensors. Measured and corrected bridge values are provided at the Sig™ pin, which can be configured as an analog voltage output or as a one-wire serial digital output. The ZACwire™ digital one-wire interface (OWI) can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSSC3015 and a specific sensor are mated digitally: fast, precise, and without the cost overhead associated with trimming by external devices or laser. Integrated diagnostics functions make the ZSSC3015 particularly well-suited for automotive applications.

Features

  • Digital compensation of sensor offset, sensitivity, temperature drift, and nonlinearity
  • Programmable analog gain and digital gain; accommodates bridges with spans < 1mV/V and high offset
  • Many diagnostic features on-chip (e.g., EEPROM signature, bridge connection checks, bridge short detection, power loss detection)
  • Independently programmable high and low clipping levels
  • 24-bit customer ID field for module traceability
  • Internal temperature compensation reference (no external components)
  • Option for external temperature compensation with addition of single diode
  • Output options: rail-to-rail ratiometric analog voltage (12-bit resolution), absolute analog voltage, ZACwire™ digital one-wire interface
  • Fast power-up to data out response, output available 5ms after power-up
  • Current consumption depends on programmed sample rate and mode: 1mA down to 300μA (typ.)
  • Fast response time: 1.4ms typical
  • High voltage protection: ≤ 30V with external JFET
  • AEC-Q100 qualified

IDT Sensor Signal Conditioner (SSC) Evaluation Kit Overview

A brief introduction and overview of IDT's sensor signal conditioner evaluation kits. Evaluation kits generally consist of three parts: a communication interface board,  a device board, and a sensor simulator board - all connected together. A sophisticated software GUI accompanies the kit, enabling an engineer to learn how to use the part rapidly, do quick prototyping, and practice calibrations.
