AD595CQ Thermocouple Amplifiers IC ANALOG DEVICES CDIP-14

The AD595CQ is a Type K Monolithic Thermocouple Amplifier with Cold Junction Compensation that combines an ice point reference with a pre-calibrated amplifier to produce a high level (10mV/°C) output directly from a thermocouple signal. 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. The AD595 is laser trimmed for type K (chromel-alumel) inputs. The temperature transducer voltages and gain control resistors are available so that the circuit can be recalibrated for the thermocouple types by the addition of two or three resistors. These terminals also allow more precise calibration for both thermocouple and thermometer applications.
