TM ZSC31010 RBic Analog Output Lite Sensor Signal Conditioner Datasheet Brief Description Benefits The ZSC31010 is a sensor signal conditioner inte- No external trimming components required grated circuit, which enables easy and precise Simple PC-controlled configuration and calibration of resistive bridge sensors via EEPROM. calibration via ZACwire One-Wire Interface When mated to a resistive bridge sensor, it will High accuracy (0.1% FSO -25 to 85C digitally correct offset and gain with the option to 0.25% FSO -50 to 150C) correct offset and gain coefficients and linearity over Single pass calibration quick and precise temperature. A second-order compensation can be Suitable for battery-powered applications enabled for temperature coefficients of gain or offset Small SOP8 package or bridge linearity. The ZSC31010 communicates via IDTs ZACwire serial interface to the host computer and is easily mass calibrated in a Available Support Windows environment. Once calibrated, the output pin Sig can provide selectable 0 to 1 V, rail-to-rail Development Kit available ratiometric analog output, or digital serial output of Mass Calibration Kit available bridge data with optional temperature data. Support for industrial mass calibration available Quick circuit customization possible for large production volumes Features Digital compensation of sensor offset, sensitivity, Physical Characteristics temperature drift, and non-linearity Accommodates differential sensor signal spans, Supply voltage 2.7 to 5.5 V, with external JFET from 3 mV/V to 105 mV/V 5.5V to 30 V Current consumption depending on adjusted ZACwire One-Wire Interface (OWI) sample rate: 0.25 mA to 1 mA Internal temperature compensation and detection Wide operational temperature: 50 to +150C via bandgap PTAT (proportional to absolute temperature) ZSC31010 Application Circuit Digital Output Output options: rail-to-rail analog output voltage, absolute analog voltage, digital ZACwire One- Wire Interface (OWI) V supply +4.5 to +5.5 V Optional sequential output of both temperature VDD and bridge readings on ZACwire digital output Bsink Fast response time, 1 ms (typical) Sig OUT/OWI ZSC31010 High voltage protection up to 30 V with VBP external JFET 10nF Vgate Chopper-stabilized true differential ADC VBN Buffered and chopper-stabilized output DAC VSS 0.1F Ground 2016 Integrated Device Technology, Inc. 1 January 20, 2016 TM ZSC31010 RBic Analog Output Lite Sensor Signal Conditioner Datasheet ZSC31010 Block Diagram JFET (optional if supply is 2.7 to 5.5 V) 5.5 V to 30 V V SUPPLY S D 0.1 mF 2.7 to 5.5 V VDD Vgate Highly Versatile Applications Temp.
