RBic Analog Output Sensor Signal dLite ZSC31015 Conditioner with Diagnostic Features Datasheet Brief Description Benefits The ZSC31015 is adjustable to nearly all piezo- No external trimming components required resistive bridge sensors. Measured and corrected Simple PC-controlled configuration and bridge values are provided at the SIG pin, which calibration via one-wire interface can be configured as an analog voltage output or as High accuracy: 0.1% FSO -25 to 85C a one-wire serial digital output. 0.25% FSO -50 to 150C The digital one-wire interface (OWI) can be used for Single-pass calibration quick and precise a simple PC-controlled calibration procedure to prog- ram a set of calibration coefficients into an on-chip Available Support EEPROM. The calibrated ZSC31015 and a specific sensor are mated digitally: fast, precise, and without Evaluation Kit available the cost overhead associated with trimming by Mass Calibration System available external devices or laser. Integrated diagnostics Support for industrial mass calibration available functions make the ZSC31015 particularly well suited for automotive applications.* Quick circuit customization possible for large production volumes Features Physical Characteristics Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity Wide operation temperature: 50C to +150C Programmable analog gain and digital gain Supply voltage 2.7 to 5.5V with external JFET, accommodates bridges with spans < 1mV/V 5.5 to 30V and high offset Small SOP8 package Many diagnostic features on chip (e.g., EEPROM signature, bridge connection checks, bridge short ZSC31015 Application Circuit detection, power loss detection) Independently programmable high and low V supply clipping levels +2.7 to +5.5 V VDD 24-bit customer ID field for module traceability Internal temperature compensation reference SIG OUT/OWI (no external components) ZSC31015 Option for external temperature compensation VBP with addition of single diode Vgate Output options: rail-to-rail ratiometric analog VBN 0.1 F VSS voltage (12-bit resolution), absolute analog voltage, digital one-wire interface Ground Fast power-up to data out response output available 5ms after power-up Current consumption depends on programmed * Not AEC-Q100-qualified. sample rate: 1mA down to 250 A (typical) Fast response time: 1ms (typical) High voltage protection up to 30V with external JFET 2016 Integrated Device Technology, Inc 1 November 14, 2016 RBic Analog Output Sensor Signal dLite ZSC31015 Conditioner with Diagnostic Features Datasheet 1 JFET ZSC31015 Block Diagram (Optional if supply is 2.7 to 5.5 V) 5.5 V to 30 V V SUPPLY S D 0.1 F VDD (2.7 to 5.5 V) Vgate Highly Versatile Applications RBic dLite 12-Bit PTAT in Many Markets Including Sensor VDD ZSC31015 DAC Diagnostics Temperature Regulator Reference Industrial Building Automation VBP TM A SIG VBN + D Office Automation 0 V to 1 V Optional Ratiometric INMUX PREAMP 14-Bit ADC OUTBUF1 Ext.
