ZSSC4175DE2B

Overview

The ZSSC4175DE2B is a sensor signal conditioner integrated circuit belonging to the ZSSC416x/ZSSC417x family, manufactured by Renesas Electronics Corporation. It is designed for highly accurate amplification and digital correction of differential bridge or voltage source sensor signals. The device features an analog pre-amplification range of 150 to 200 and utilizes a 16-bit RISC microcontroller for offset, gain, nonlinearity, and temperature drift compensation. Configuration data and calibration coefficients are stored in non-volatile memory (NVM). Measured values can be read via a digital SENT interface or an I²C™ interface. The component supports OWI for end-of-line calibration through the data output pin.

Feature Summary

• Digital compensation of sensor offset, sensitivity, higher-order nonlinearity, and temperature coefficients using an internal 16-bit RISC microcontroller.
• Configurable analog-to-digital conversion with resolution adjustable from 12 to 16 bits, supporting large sensor offset correction via digital zooming.
• Supports dual thermocouple interfaces with diagnostics and cold-junction temperature compensation using an internal temperature sensor.
• Optimized for automotive environments with overvoltage protection up to +/-18V, reverse polarity protection, and excellent electromagnetic compatibility.

Applications

• Dual thermocouple temperature measurement systems
• Automotive pressure sensors and strain gauges
• Industrial NTC/PTC RTD temperature sensing
• Thermocouple modules requiring cold-junction compensation
