The AD594CD from Analog Devices is a complete instrumentation amplifier and thermocouple cold junction compensator on a single monolithic chip. It is pretrimmed for Type J thermocouples and can also be used with Type T inputs. The device offers a high-level output of 10mV/°C directly from a thermocouple signal, simplifying temperature measurement.
Key features include built-in ice point compensation, a wide power supply range of ±5V to ±15V, and low power consumption of less than 1mW typical. It also incorporates a thermocouple failure alarm with TTL drive capability. The AD594CD is laser wafer trimmed to 1°C calibration accuracy and operates over a temperature range of -55°C to 125°C.
This component is available in a 14-pin CDIP package suitable for through-hole mounting. Its flexible pinout allows for operation as a linear amplifier-compensator or as a switched output setpoint controller. The AD594CD is ideal for applications requiring accurate and direct temperature readings from thermocouples.
