The AD594AQ from Analog Devices Inc. is a complete instrumentation amplifier and thermocouple cold junction compensator integrated circuit. It is pretrimmed for Type J thermocouples and can also be used with Type T thermocouple inputs. This device provides a high-level, low-impedance voltage output of 10 mV/°C, directly from a thermocouple signal, simplifying temperature measurement.
Key features include built-in ice point compensation, a thermocouple failure alarm, and laser wafer trimming for calibration accuracy. The AD594AQ operates from a wide power supply range of +5V to ±15V and consumes low power, typically less than 1 mW. It is designed for operation between -55°C and 125°C.
This component is housed in a 14-pin CERDIP package and is suitable for through-hole mounting. Its flexible pinout allows for operation as a linear amplifier-compensator or as a switched output setpoint controller. The AD594AQ is ideal for applications requiring accurate and direct temperature readings from thermocouples.
