Adafruit 1778 Analog Output K-Type Thermocouple Amplifier - AD8495 Breakout

Adafruit 1778 Analog Output K-Type Thermocouple Amplifier - AD8495 Breakout Description

The Adafruit K-Type Thermocouple Amplifier offers a quick and easy way of hooking up a thermocouple to your next project. Thermocouples need a cold-compensation reference and a good amplifier which is where the AD8495 chip comes in. It handles all the electrical complications and presents you with a single analogue output which you can feed into your microcontroller or other circuitry if you are going old school. In fact, this amplifier is so simple that Adafruit have silk-screened everything you need to know on the back of the board, including the formula for calculating the temperature.

Supplied as a fully assembled and tested thermocouple amplifier board plus a strip of 0.1in header pins and a 2-way screw terminal block for you to solder on as required. Adafruit only recommend this amplifier for K-type thermocouples although the datasheet mentions J-type. Feel free to experiment, but we only support its use with K-type thermocouples. We supply the thermocouples separately.
