Resistive Sensor Signal Conditioner with Analog Output and Diagnostic Features

The ZSC31015 (RBicdLite™) is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM. The ZSC31015 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 digital one-wire interface can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSC31015 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 ZSC31015 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
  • Digital calibration and configuration via one-wire interface quick and precise
  • 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, digital one-wire-interface
  • Supply voltage 2.7 to 5.5V, with external JFET, 5.5 to 30V
  • Fast power-up to data output response, output available 5ms after power up
  • Current consumption depends on programmed sample rate: 1mA down to 250
