Brief Description
The ZSC31010 is a sensor signal conditioner integrated circuit, which enables easy and precise calibration of resistive bridge sensors via EEPROM. When mated to a resistive bridge sensor, it will digitally correct offset and gain with the option to correct 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. The 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 pin Sig™ can provide selectable 0 to 1 V, 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)
• Output options: rail-to-rail analog output voltage,
   absolute analog voltage, digital ZACwire™ OneWire Interface (OWI)
• Optional sequential output of both temperature
   and bridge readings on ZACwire™ digital output
• Fast response time, 1 ms (typical)
• High voltage protection up to 30 V with
   external JFET
• Chopper-stabilized true differential ADC
• Buffered and chopper-stabilized output DAC
