Data Sheet Rev. 1.11 / June 2011 ZSSC3008 Sensor Signal Conditioner with Diagnostics ZSSC3008 Sensor Signal Conditioner with Diagnostics Brief Description Benefits The ZSSC3008 is a sensor signal conditioner IC that PC-controlled configuration and calibration via is adjustable to nearly all piezo-resistive bridge sen- one-wire interface simple, low cost sors. Measured and corrected bridge values are pro- High accuracy (0.1% FSO -25 to 85C vided at the SIG pin, which can be configured as 0.25% FSO -40 to 125C) an analog voltage output or as a one-wire serial dig- Single-pass calibration quick and precise ital output. The digital one-wire interface (OWI) can be used for Available Support a simple PC-controlled calibration procedure to pro- gram a set of calibration coefficients into an on-chip Development Kit available EEPROM. The calibrated ZSSC3008 and a specific Multi-Unit Calibrator Kit available sensor are mated digitally: fast, precise, and without Support for industrial mass calibration available the cost overhead associated with trimming by exter- Quick circuit customization possible for large nal devices or laser. Integrated diagnostics functions production volumes make the ZSSC3008 particularly well-suited for auto- motive applications.* Physical Characteristics Features Wide operation temperature: 40C to +125C Digital compensation of sensor offset, sensitivity, Supply voltage 2.7 to 5.5V with external JFET, and non-linearity 5.5 to 30V Programmable analog gain and digital gain Small SOP8 package accommodates bridges with spans < 1mV/V and high offset ZSSC3008 Application Circuit Many diagnostic features on chip (e.g., EEPROM signature, bridge connection checks, bridge short V supply detection, power loss detection) +2.7 to +5.5 V VDD Independently programmable high and low clipping levels SIG OUT/OWI 24-bit customer ID field for module traceability ZSSC3008 Output options: rail-to-rail ratiometric analog VBP voltage (12-bit resolution), absolute analog Vgate voltage, digital one-wire interface VBN 0.1 F VSS Fast power-up to data out response output available 5ms after power-up Ground Current consumption depends on programmed sample rate: 1mA down to 250 A (typical) Fast response time: 1ms (typical) * Not AEC-Q100-qualified.
