Overview
Sensor Signal Conditioner Family ZSSC416x / ZSSC417x Feature Sheet Brief Description IDT’s ZSSC416x/ZSSC417x is a family of CMOS integrated circuits for highly accurate amplification and sensor-specific correction of differential bridge sensor signals.
Featuring a maximum analog preamplification in the range of 150 to 200, this product is adjustable to nearly all resistive bridges as well as voltage source sensor types; e.
g.
, thermocouples.
Digital compensation of offset, sensitivity, temperature drift, and nonlinearity is accomplished with a 16-bit RISC microcontroller.
Calibration coefficients and configuration data are stored in the ZSSC416x/ ZSSC417x non-volatile memory (NVM), which is reliable in automotive applications.
Measured values can be read via a digital SENT or I2C™* interface.
The SENT interface enables transmission of sensor data via its fast channel as well as supplementary data via its “slow” Serial Data Message (SDM) channel using only one output pin.
Endof-line calibration is supported via an I2C™ interface or via a One-Wire Interface (OWI) through the data output pin (DOUT).
The ZSSC416x/ ZSSC417x 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 ZSSC416x/ZSSC417x is optimized for automotive environments by overvoltage and reverse polarity protection circuitry, excellent electromagnetic compatibility, and multiple diagnostic features.
Features  Differential sensor bridge or voltage source inputs  Internal or external temperature sensors, selectable for conditioning of sensor input signals or temperature output  Digital compensation of offset, gain, and higher order nonlinearity as well as temperature coefficients of measured sensor input signals  Operating temperature range: -40°C to 150°C  Accuracy: ±0.
25% FSO @ -40°C to 125°C  NVM memory for configuration data, user configurable me...
