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. * Accuracy ±1°C at 25°C, ±2°C from -25 to +400°C * Sensor temperature range -25 to +400°C * Input voltage 3 to 18V DC * Dimensions 20 x 16 x 2mm (0.8 x 0.6 x 0.08in.) * Adafruit part no.: 1778 *Customers looking to resell on eBay or Amazon should contact Adafruit directly. https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2024-11-14 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2025-03-28 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2025-05-29 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2025-06-17 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2025-07-26 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2025-09-25 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2026-05-11 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2026-06-02 https://elecena.pl/product/27279022/adafruit-1778-analog-output-k-type-thermocouple-amplifier-ad8495-breakout 2026-07-18
