ZSC31010 RBicLite™ Analog Output Sensor Signal Conditioner Brief Description Benefits 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 ZMDI’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. Available Support 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 Development Kit available Mass Calibration Kit available Support for industrial mass calibration available Quick circuit customization possible for large production volumes Physical Characteristics No external trimming components required Simple PC-controlled configuration and calibration via ZACwire™ One-Wire Interface High accuracy (±0.1% FSO @ -25 to 85°C; ±0.25% FSO @ -50 to 150°C) Single pass calibration – quick and precise Suitable for battery-powered applications Small SOP8 package Supply voltage 2.7 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 temperature: –50 to +150°C ZSC31010 Application Circuit – Digital Output Vsupply +4.5 to +5.5 V VDD Bsink Sig™ OUT/OWI ZSC31010 VBP 10nF Vgate VBN VSS 0.1µF Ground For more information, contact ZMDI via [email protected]. © 2013 Zentrum Mikroelektronik Dresden AG — Rev. 2.91 — November 1, 2013.
