Sensor Signal Conditioner Family

Feature Sheet

ZSSC416x /

ZSSC417x

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

I C™* 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 I C™ 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.
