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 pre-
amplification 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, temper-
ature 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 trans-
mission of sensor data via its fast channel as well as
supplementary data via its “slow” Serial Data Mes-
sage (SDM) channel using only one output pin. End-
of-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 automo-
tive environments by overvoltage and reverse
polarity protection circuitry, excellent electromag-
netic compatibility, and multiple diagnostic features.
Features
Differential sensor bridge or voltage source inputs
Internal or external temperature sensors, select-
able 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 con-
figurable measurement and conditioning function,
and user-selected data

standard using fast and SDM data channels
Supports output of one or more sensor signals
and product identification via a single SENT
interface connection
