ADI AD595AQ

热电偶放大器-55°C ~ 125°C

Overview

The AD595AQ is a Complete Instrumentation Amplifier with thermocouple cold junction compensator on a monolithic chip. It combines an ice point reference with a pre-calibrated amplifier to produce a high level (10mV/°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 set-point controller using either fixed or remote set-point 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. It 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 drive capability. It can be powered from a single ended supply (including +5V) and by including a negative supply, temperatures below 0°C can be measured.
