Analog Devices' AD8495 and AD8497 are precision instrumentation amplifiers with thermocouple cold junction compensators on an integrated circuit. They produce a high-level (5mV/°C) output directly from a thermocouple signal by combining an ice point reference with a pre-calibrated amplifier. They can be used as standalone thermometers or as switched output set point controllers, using a fixed or remote set point control. The AD8495 and AD8497 can be powered from a single-ended supply (less than 3V) and can measure temperatures below 0°C by offsetting the reference input. To minimize self-heating, an unloaded AD849x typically operates with a total supply current of 180µA. However, it is also capable of delivering in excess of ±5mA to a load.
