AD594 IC monolithic thermocouple amplifier AD 594 594

Product Overview

The AD594 and AD595 are complete, monolithic instrumentation amplifiers integrated with thermocouple cold junction compensators. They combine an ice-point reference with a precalibrated amplifier to convert low-level thermocouple signals directly into a high-level voltage output of 10 mV/°C. These devices are designed for versatility, allowing them to function as linear amplifier-compensators, switched output setpoint controllers, or stand-alone Celsius transducers.
