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.

2 Electrical Characteristics
Important note: The absolute maximum ratings given in section 2.1 are stress ratings only. The ZSSC4151 might
not function or be operable above the recommended operating conditions. Stresses exceeding the absolute
maximum ratings might also damage the device. In addition, extended exposure to stresses above the
recommended operating conditions might affect device reliability. IDT does not recommend designing to the
specifications given under “Absolute Maximum Ratings.”
Important note: The operating conditions given in section 2.2 set the conditions over which IDT specifies device
operation. These are the conditions that the application circuit should provide to the device for it to function as
intended. Unless otherwise noted, the limits for parameters that appear in the operating conditions section are
used as test conditions for the limits given in the electrical characteristics (section 2.3), operating conditions, and
interface characteristics and nonvolatile memory sections.
