ZSC31015 Datasheet | Renesas

RBicd Lite™ Analog Output Sensor Signal Conditioner with Diagnostic Features Brief Description 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. 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.- Features - Digital pensation of sensor offset, sensitivity, temperature drift, and non-linearity - Programmable analog gain and digital gain; acmodates bridges with spans < 1m V/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 pensation reference (no external ponents) - Option for external temperature pensation 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: 1m A down to 250A (typical) - Fast response time: 1ms (typical) - High voltage protection up to 30V with external JFET Benefits - No external trimming ponents 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 - Single-pass calibration - quick and...
