IDT Launches ZSSC4175 Sensor Signal Conditioner

Integrated Device Technology, Inc. (IDT) has launched its new ZSSC4175 sensor signal conditioner for dual thermocouples, which is designed for automotive exhaust system applications. It provides accurate amplification and sensor-specific correction of thermocouple signals to ensure very precise measurement of exhaust gas temperatures – data that is used by engine management systems to reduce harmful emissions and improve fuel economy.

The ZSSC4175 is optimized for AEC-Q100 qualified automotive environments with overvoltage and reverse polarity protection circuitry, excellent electromagnetic compatibility, multiple diagnostic features and a -40°C to 150°C operating range. It has dual inputs for thermocouple signals and uses a 16-bit RISC microcontroller to digitally compensate for offset, sensitivity, temperature drift and nonlinearity. The ZSSC4175 stores calibration coefficients and configuration data in an integrated non-volatile memory (NVM) IC that is reliable in automotive applications.

Key features of the ZSSC4175 include an internal cold junction temperature sensor that is pre-calibrated, which keeps assembly costs low as no trimming by external devices or lasers is needed. Another feature is its on-chip cold-junction compensation, which enables the ZSSC4175 to achieve best-in-class accuracy over a measurement range of -40°C to 1250°C. It also offers N-type thermocouple calibration support by mathematical model.
