Short-Form Datasheet ZSSC4132 Automotive Resistive Sensor Signal Conditioner with LIN Interface Description Features The ZSSC4132 is member of the Renesass family Differential bridge sensor input and on-chip or external temperature sensors, selectable for of CMOS integrated circuits for highly accurate conditioning of sensor input signal and/or amplification and sensor-specific correction of temperature output differential bridge sensor signals. Featuring a maximum analog pre-amplification in the range of Digital compensation of offset, gain, and higher order nonlinearity as well as temperature 150 to 200, the ZSSC4132 is adjustable to nearly all coefficients of measured bridge sensor input resistive bridges as well as voltage-source sensor signal types. Operating temperature range -40C to 150C Digital compensation of offset, sensitivity, Accuracy 0.5% FS at -40C to 150C temperature drift, and nonlinearity is accomplished by a 16-bit RISC microcontroller. Calibration NVM memory for configuration and calibration coefficients and configuration data are stored in the data, and for configurable measurement and ZSSC4132 non-volatile memory (NVM), which is conditioning functionality reliable in automotive applications. LIN interface based on LIN Specification Package 2.2A Measured values are provided via a LIN interface according to the LIN Specification Package 2.2A. Supports output of one or more sensor signals and product identification via a single LIN The LIN interface enables transmission of sensor interface connection data as well as transmission of supplementary data. End-of-line calibration is also supported through this Configurable for nearly all resistive bridge output pin based on the LIN protocol. The sensors ZSSC4132 and the calibration equipment One-pass end-of-line calibration algorithm communicate digitally, so the noise sensitivity is minimizes production costs greatly reduced. Digital calibration helps keep No external trimming or components required assembly costs low as no trimming by external Supply voltage: 7V to 18V devices or lasers is needed. Protection up to 40V (with external diode at The ZSSC4132 is optimized for automotive VBAT) environments by overvoltage and reverse-polarity Input span: 1 to 900 mV/V protection circuitry, excellent electromagnetic compatibility, and multiple diagnostic features.
