AD594CQ Description

Short technical summary and product information.

The Analog Devices AD594CQ is a complete monolithic instrumentation amplifier and thermocouple cold junction compensator. It is pretrimmed for Type K thermocouples and offers a high-level output of 10 mV/°C. The device features built-in ice point compensation, a wide power supply range of ±5V to ±15V, and low power consumption of less than 1 mW typical.

 

With a laser-trimmed calibration accuracy of ±1°C, the AD594CQ is suitable for precise temperature measurements. It includes a thermocouple failure alarm and can operate as a stand-alone Celsius transducer. The amplifier is available in a 14-pin CDIP (0.300", 7.62mm) package, designed for through-hole mounting.

 

This component is ideal for applications requiring accurate temperature monitoring using thermocouple inputs. Its integrated features simplify circuit design by combining amplification, compensation, and output buffering into a single IC.
