The AD8497ARMZ-R7 is an integrated circuit (IC) component designed for precision thermocouple amplification and cold-junction compensation. It allows for accurate measurement of temperature in various applications, such as industrial control systems, HVAC equipment, and process monitoring.
Key Features:
1. Thermocouple Amplification: The AD8497ARMZ-R7 is specifically designed to amplify the small voltage generated by a thermocouple. It provides a low-noise, high-gain amplification stage to accurately measure temperature.
2. Cold-Junction Compensation: This IC includes an integrated cold-junction compensation (CJC) sensor. The CJC sensor senses the ambient temperature at the point where the thermocouple wires connect to the IC. This compensates for temperature variations at the measurement point, ensuring accurate temperature readings.
3. High Accuracy: The AD8497ARMZ-R7 offers high accuracy over a wide temperature range. It provides a maximum nonlinearity error of ±0.5°C and a maximum offset voltage of ±3µV/°C.
4. Low Power Consumption: It operates at low power, making it suitable for battery-operated devices or applications where power efficiency is essential. The typical supply current is only 120µA.
5. Voltage Output: This IC provides a voltage output proportional to the thermocouple temperature. It offers a linear relationship between temperature and output voltage, simplifying temperature measurement and interpretation
