Additional Details:

The AD595CQZ is designed to work with K-type thermocouples, but can be adapted for use with other thermocouple types with appropriate external circuitry. The amplifier features a high common-mode rejection ratio (CMRR) to eliminate noise. The device also includes a built-in open thermocouple detector. The AD595CQZ operates from a single +5 V supply and is available in a 14-pin DIP package.
