Temperature Sensors
Find analog and digital temperature sensors that sense and measure temperature with precise accuracy and reliability. ADI digital temp sensors achieve up to ±0.25°C accuracy over a wide temperature range, are NIST traceable, and are plug-in ready requiring no additional signal conditioning or calibration. Additionally, ADI digital temp sensors may integrate DACs, ADCs, references, and limit alarm registers. Choose an ADI analog temp sensor for simple voltage or current out functionality. A range of interfaces are available including I2C, SPI and PWM (for digital products) and current and voltage (for analog products).
ADI thermocouple amplifiers with integrated cold junction compensation are easy to use and provide an accurate temperature output for thermocouple signal conditioning.
Engineered. Tested. Ready to Integrate.
