Datasheet
Brief Description
The ZSSC3138 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 on chip
(EEPROM).
The ZSSC3138 offers a maximum analog gain of
420 and two offset compensation features. These fit
perfectly with the requirements of ceramic thick-film-
based sensor elements as well as strain gauges.
The high amplification in combination with the offset
compensation offers the capability to set up ceramic
thick-film-based sensor applications without laser
trimming, which leads to better long-term stability.
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 precise
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
