ZSSC4151 Datasheet
1 Brief Description
The ZSSC4151 sensor signal conditioner (SSC) is a CMOS integrated circuit for highly accurate amplification and
sensor-specific correction of bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperature
drift, and non-linearity is accomplished via an internal 16-bit RISC microcontroller running a correction algorithm
with calibration coefficients stored in an EEPROM.
The ZSSC4151 is adjustable to nearly all bridge sensor types. Measured values are provided at the analog
voltage 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 of
calibration coefficients into an on-chip EEPROM. The specific sensor and the ZSSC4151 can be quickly
calibrated together. The ZSSC4151 and the calibration equipment communicate digitally, so the noise sensitivity
is greatly reduced. Digital calibration helps keep assembly cost low as no trimming by external devices or lasers is
needed.
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.
