Analog Devices AD594/AD595 Monolithic Thermocouple Amplifiers Specification Sheet
The AD594 and AD595 are monolithic thermocouple amplifiers that integrate cold‑junction compensation, high‑gain amplification, and a low‑impedance voltage output (10 mV/°C). They are laser‑trimmed for Type J (AD594) or Type K (AD595) thermocouples and can also be configured for other thermocouple types through external recalibration.
The devices operate from a wide supply range, support both single‑supply (+5 V) and dual‑supply configurations, and include a thermocouple failure alarm. Key specifications such as power‑supply range, quiescent current, calibration error, and operating temperature range are listed in the specification tables.
