ANALOG DEVICES Monolithic Thermocouple Amplifiers with Cold Junction Compensation AD594/AD595 handbook
Update: 30 September, 2023
The AD594/AD595 is an integrated temperature sensor with cold junction compensation, which can be used with Type J, Type K and Type T thermocouples. It combines an ice point reference with a precalibrated amplifier to produce a high level (10 mV/°C) output directly from a thermocouple signal. Pin-strapping options allow it to be used as a linear amplifier-compensator or as a switched output setpoint controller using either fixed or remote setpoint control. It can be used to amplify its compensation voltage directly, thereby converting it to a stand-alone Celsius transducer with a low impedance voltage output. The AD594/AD595 includes a thermocouple failure alarm that indicates if one or both thermocouple leads become open. The alarm output has a flexible format which includes TTL driver output, integrated circuit driver output and passive decoder output.
