AD8497ARMZ-R7 Description

Short technical summary and product information.

The AD8497ARMZ-R7 is a precision thermocouple amplifier from Analog Devices designed for K-type thermocouples. It includes internal cold junction compensation and provides a calibrated 5 mV/°C analog output. The device is laser trimmed for high accuracy and ambient temperature rejection.

 

Key electrical specifications include a wide single supply range of 2.7 V to 36 V (or dual ±2.7 V to ±18 V), low supply current of 180 µA typical, and differential input. The output is analog with a scale of 5 mV/°C. It also features thermocouple break detection.

 

The amplifier is optimized for ambient reference junction temperatures from 25°C to 100°C, while the measurement junction covers the full K-type range. It is housed in a compact 8-lead MSOP package for surface mount assembly. The device is suitable for temperature measurement, setpoint control, and cold junction compensation applications.
