AD849x Precision Thermocouple Amplifiers

Analog Devices AD849x Precision Thermocouple Amplifiers with Cold Junction Compensation produce a high level (5mV/°C) output directly from a thermocouple signal by combining an ice point reference with a precalibrated amplifier. The AD849x has the option to be used as a standalone thermometer or as switched output setpoint controller using a fixed or remote setpoint control. The devices can measure temperatures below 0°C by offsetting the reference input. Additionally, the AD849x can be powered from a single-ended supply (less than 3V).
