The MAX31855KASA+ is a thermocouple-to-digital converter with a cold junction compensated output from Analog Devices. It supports 8 different kinds of thermocouples (Type K, J, N, R, S, T, E, B) and it provides a 'select' pin to enable easy thermocouple range selection. The device has a high precision 16-bit digital output which can be read by a microcontroller or other digital devices. It also has a 0.25°C resolution and a 0.5°C accuracy. The MAX31855KASA+ operates over a wide temperature range (-55°C to +150°C) and comes in a tiny leadless 4mm x 4mm QFN-16 package. It can be used in a variety of applications such as measurement and control systems for industrial and consumer temperature sensing applications.
