Adafruit AD8495 Analogue Output K-Type Thermocouple Amplifier Breakout
- Adafruit 269, The Adafruit MAX31855K Thermocouple Amplifier offers a quick & easy way of hooking up a thermocouple to your next microcontroller project. Thermocouples need a cold-compensation reference & a good amplifier which is where the MAX31855K chip comes in. It handles all the electrical complications & provides you with an SPI channel you can interrogate as needed. This board has been enhanced over time & now has ferrite beads & a filter capacitor to improve the stability, plus an onboard regulator, & level shifting circuitry for 5V compatibility. A very useful, mature gadget. Supplied as a fully assembled & tested thermocouple amplifier board plus a strip of 0.1in header pins & 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 several other types. Feel free to experiment, but we only support its use with K-type thermocouples. We supply the thermocouples separately. Adafruit 269 MAX31855K Thermocouple Amplifier
