Adafruit AD8495 Analogue Output K-Type Thermocouple Amplifier Breakout

The Adafruit K-Type Thermocouple Amplifiers offer 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 these breakout boards come in. They handle all the electrical complications and provide you with either an analogue (73-5399) or digital SPI output (73-5329) which you can feed into your microcontroller or other circuitry if you are going old school.

The analogue output amplifier (73-5399) has a measurement temperature range of -24 to +400°C while the digital output (73-5329) amplifier has a -200 to +1350°C range.

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 these amplifiers for K-type thermocouples although the datasheets mentions other types. Feel free to experiment, but we only support their use with K-type thermocouples. We supply the thermocouples separately.

• Choose from analogue or SPI output
