Thermocouple and Thermistor Interface

Maxim Integrated Products provides the largest selection of thermal-measurement ICs in the industry. Maxim's thermocouple and thermistor digital converters provide high-performance integrated solutions for a wide range of applications. Thermocouple digital converters interface with type-K thermocouples and provide an SPI™ output. Thermistor digital converters operate with up to four negative temperature coefficient (NTC) thermistors.
