Analog Output K-Type Thermocouple Amplifier - AD8495 Breakout
The AD8495 from Analog Devices is an analog-output K-type thermocouple amplifier on a compact breakout board. Simply power the board with 3–18V DC, connect a K-type thermocouple to the terminal block, and read the temperature as a voltage on the OUT pin — no digital protocols or complex configuration needed.
Temperature conversion is straightforward: Temperature = (Vout - 1.25) / 0.005 V. For example, 1.5V output = 50°C. The board includes a TLVH431 1.25V precision voltage reference for accurate cold-junction compensation.
Key Features
