Automotive Resistive Sensor Signal Conditioner with LIN Interface
Automotive Resistive Sensor Signal Conditioner with LIN Interface Description Features The ZSSC4132 is member of the Renesas’s 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, the ZSSC4132 is adjustable to nearly all
resistive bridges as well as voltage-source sensor
Digital compensation of offset, sensitivity,
temperature drift, and nonlinearity is accomplished
by a 16-bit RISC microcontroller. Calibration
coefficients and configuration data are stored in the
ZSSC4132 non-volatile memory (NVM), which is
reliable in automotive applications.
Measured values are provided via a LIN interface
according to the LIN Specification Package 2.2A.
The LIN interface enables transmission of sensor
data as well as transmission of supplementary data.
End-of-line calibration is also supported through this
output pin based on the LIN protocol. The
ZSSC4132 and the calibration equipment …
