ZSSC3170 - Automotive Sensor Signal Conditioner

Description

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.

Features

  • Complies with LIN specifications 1.3 / 2.0 / 2.1.
  • Configurable LIN publisher frame content.
  • Data conversion rate of up to 430Hz fully utilizes the maximum LIN channel capacity of 20kbit/s.
  • PWM high-side and low-side switches, support for LIN communication for end-of-line calibration.
  • Digital compensation of offset, gain, temperature effects up to 2nd order, and nonlinearity up to 3rd order. Compensation of temperature sensor offset, gain, and nonlinearity up to 2nd orde.

Automotive Sensor Signal Conditioner with LIN and PWM Interface ZSSC3170 Datasheet Brief Description 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 automotive applications. Measured values are provided by one of the digital LIN or PWM interfaces. Each interface can support end-of-line calibration using the sensor output.
