ZSC31015 RBicdLite™ Analog Output Sensor Signal Conditioner w/ Diagnostic Features Brief Description Benefits The ZSC31015 is adjustable to nearly all piezoresistive bridge sensors. Measured and corrected bridge values are provided at the SIG™ pin, which can be configured as an analog voltage output or as a one-wire serial digital output. No external trimming components required Simple PC-controlled configuration and calibration via one-wire interface High accuracy: ±0.1% FSO @ -25 to 85°C; ±0.25% FSO @ -50 to 150°C The digital one-wire interface (OWI) can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSC31015 and a specific sensor are mated digitally: fast, precise, and without the cost overhead associated with trimming by external devices or laser. Integrated diagnostics functions make the ZSC31015 particularly well suited for automotive applications.* Single-pass calibration – quick and precise Available Support Evaluation Kit available Mass Calibration System available 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 Programmable analog gain and digital gain; accommodates bridges with spans < 1mV/V and high offset Many diagnostic features on chip (e.g., EEPROM signature, bridge connection checks, bridge short detection, power loss detection) Independently programmable high and low clipping levels 24-bit customer ID field for module traceability Internal temperature compensation reference (no external components) Option for external temperature compensation with addition of single diode Output options: rail-to-rail ratiometric analog voltage (12-bit resolution), absolute analog voltage, digital one-wire interface Fast power-up to data out response; output available 5ms after power-up Current consumption depends on programmed sample rate: 1mA down to 250A (typical) Fast response time: 1ms (typical) High voltage protection up to 30V with external JFET Physical Characteristics Wide operation temperature: –50°C to +150°C Supply voltage 2.7 to 5.5V; with external JFET, 5.5 to 30V Small SOP8 package ZSC31015 Application Circuit Vsupply +2.7 to +5.5 V VDD SIG™ OUT/OWI ZSC31015 VBP Vgate VBN VSS 0.1 F Ground * Not AEC-Q100-qualified.
