ZSSC3170: Automotive Sensor Signal Conditioner with LIN and PWM Interface

The ZSSC3170 is a CMOS integrated circuit for highly accurate amplification
and sensor specific correction of bridge sensor signals. Featuring a
maximum analog gain of 420, as well as extended offset compensation
capabilities, the ZSSC3170 is adjustable to nearly all resistive bridge
sensor types.

Digital compensation of offset, sensitivity, temperature drift, and
nonlinearity is accomplished via a 16-bit RISC microcontroller.
Conditioning coefficients are stored in an EEPROM certified for automot
