Resistive Sensor Signal Conditioner with Analog Output

The ZSC31010 is a CMOS integrated circuit, which enables easy and precise calibration of resistive bridge sensors via EEPROM. When mated to a resistive bridge sensor, it will digitally calibrate offset and gain with the option to calibrate offset and gain coefficients and linearity over temperature. A second-order compensation can be enabled for temperature coefficients of gain or offset or bridge linearity. ZSC31010 communicates via IDT's ZACwire™ serial interface to the host computer and is easily mass calibrated in a Windows™ environment. Once calibrated, the output SIG™ pin can provide selectable 0 to 1 V absolute analog output; rail-to-rail ratiometric analog output; or digital serial output of bridge data with optional temperature data.

Features

  • Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity
  • Accommodates differential sensor signal spans from 3 mV/V to 105 mV/V
  • ZACwire™ one-wire interface (OWI)
  • Internal temperature compensation and detection via bandgap PTAT (proportional to absolute temperature)
  • Optional sequential output of both temperature and bridge readings on ZACwire™ digital output
  • Output options: ratiometric analog voltage, absolute analog voltage, digital one-wire-interface
  • Supply voltage 2.7V to 5.5 V, with external JFET 5.5V to 30 V
  • Current consumption, depending on adjusted sample rate, 0.25 mA to 1 mA
  • Wide operational range -50°C to +150°C
  • Fast response time 1 ms
  • High voltage protection up to 30V with external JFET
  • Buffered and chopper-stabilized output DAC
