Data Sheet Rev. 2.8 / May 2011 ZSC31010 RBic Low-Cost Sensor Signal Conditioner Lite ZSC31010 RBic Low-Cost Sensor Signal Conditioner Lite Brief Description Benefits The RBic ZSC31010 is a sensor signal condi- No external trimming components required Lite tioner integrated circuit, which enables easy and pre- PC-controlled configuration and calibration via cise calibration of resistive bridge sensors via ZACwire One-Wire Interface simple, low cost EEPROM. When mated to a resistive bridge sensor, High accuracy (0.1% FSO -25 to 85C it will digitally correct offset and gain with the option 0.25% FSO -50 to 150C) to correct offset and gain coefficients and linearity Single pass calibration quick and precise over temperature. A second-order compensation can Suitable for battery-powered applications be enabled for temperature coefficients of gain or Small SOP8 package offset or bridge linearity. The RBic communi- Lite cates via ZMDIs 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 Multi-Unit Calibrator 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, temperature drift, and non-linearity Physical Characteristics Accommodates differential sensor signal spans, Supply voltage 2.7 to 5.5 V, with external JFET from 1.2 mV/V to 60 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 Optional sequential output of both temperature +4.5 to +5.5 V and bridge readings on ZACwire digital output VDD Bsink Fast response time, 1 ms (typical) TM Sig OUT/OWI High voltage protection up to 30 V with ZSC31010 external JFET VBP Chopper-stabilized true differential ADC Vgate VBN Buffered and chopper-stabilized output DAC 0.1 F VSS Ground 2011 Zentrum Mikroelektronik Dresden AG Rev. 2.8 All rights reserved.
