ZSSC4151AE2V Brief Description
The ZSSC4151 sensor signal conditioner (SSC) is a CMOS integrated circuit for highly accurate amplification andsensor-specific correction of bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperaturedrift, and non-linearity is accomplished via an internal 16-bit RISC microcontroller running a correction algorithmwith calibration coefficients stored in an EEPROM.The ZSSC4151 is adjustable to nearly all bridge sensor types. Measured values are provided at the analogvoltage output and at the digital I2C™* or ZACwire™ interface, also referred to as the One-Wire Interface (OWI).The digital interfaces can be used for a simple PC-controlled calibration procedure in order to program a set ofcalibration coefficients into an on-chip EEPROM. The specific sensor and the ZSSC4151 can be quicklycalibrated together. The ZSSC4151 and the calibration equipment communicate digitally, so the noise sensitivityis greatly reduced. Digital calibration helps keep assembly cost low as no trimming by external devices or lasers isneeded.The ZSSC4151 is optimized for automotive environments by overvoltage and reverse-polarity protection circuitry,excellent electromagnetic compatibility, full automotive temperature range, and multiple diagnostic features.Figure 1.1 provides a block diagram of the ZSSC4151. Refer to section 5 for definitions of abbreviations.Figure 1.1 ZSSC4151 Block Diagram
