ZSSC3135 Sensor Signal Conditioner for Piezoresistive Bridge Sensors Datasheet Brief Description Benefits The ZSSC3135 is a member of the ZSSC313x Family approach offers the best fitting IC selec- family of CMOS integrated circuits designed for tion to build cost-optimized applications automotive/industrial sensor applications. All family No external trimming components required members are well suited for highly accurate amp- Low number of external components needed lification and sensor-specific correction of resistive PC-controlled configuration and one-pass/ bridge sensor signals. An internal 16-bit RISC TM end-of-line calibration via IC* or ZACwire microcontroller running a correction algorithm interface: simple, cost-efficient, quick, and pre- compensates sensor offset, sensitivity, temperature cise drift, and non-linearity of the connected sensor High accuracy: 0.25% FSO** -25 to +85C element. The required calibration coefficients are 0.5% FSO -40 to +125C stored by the one-pass calibration procedure in an Optimized for automotive/industrial environments on-chip EEPROM. due to robust protection circuitries, excellent The ZSSC3135 is specially designed for piezo- electromagnetic compatibility and AEC-Q100 resistive bridge sensor elements. The amplification qualification stage with an analog gain of 105 in combination with optional temperature compensation via an external temperature sensor meets or exceeds the require- Available Support ments of piezoresistive sensor applications.
