ZSSC3131
Datasheet
Brief Description
The ZSSC3131 is a member of the ZSSC313x
product family of CMOS integrated circuits designed
for automotive/ industrial sensor applications. All
family members are well suited for highly-accurate
amplification and sensor-specific correction of
resistive bridge sensor signals. An internal 16-bit
RISC microcontroller running a correction algorithm
compensates sensor offset, sensitivity, temperature
drift, and non-linearity of the connected sensor
element. The required calibration coefficients are
stored by the one-pass calibration procedure in an
on-chip EEPROM.
The ZSSC3131 is optimized for simple switch and
cost-sensitive sensor applications. The integrated
adjustable digital filter enables building fast-switch-
ing real-time applications as well as stabilized
applications for switching input signals that are
unstable or disrupted.
Benefits
Family approach offers the best fitting IC selec-
tion to build cost-optimized applications
No external trimming components required
Low number of external components needed
PC-controlled configuration and One-Pass/ end-
of-line calibration via I²C™* or ZACwire™
interface: Simple, cost-efficient, quick, and pre-
cise
High accuracy (0.25% FSO** @ -25 to +85°C;
0.5% FSO @ -40 to +125°C)
Optimized for automotive/industrial environments
due to robust protection circuitries, excellent
electromagnetic compatibility, and AEC-Q100
qualification
