AD597ARZ

Overview

The AD597ARZ is a thermocouple signal conditioner integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 5 V to 30 V and consumes a static current of 300 µA. The device provides an analog output with a maximum output voltage of 28 V and an output current capability of 5 mA. It features a gain-bandwidth product of 15 kHz and maintains an accuracy of ±4°C. The component is housed in an SOIC-8 surface-mount package, measuring 5 mm in length, 4 mm in width, and 1.5 mm in height. It supports operation across a temperature range from -40 °C to +125 °C.

Feature Summary

• Integrates cold junction compensation and linearization for direct thermocouple interfacing
• Provides amplified analog output compatible with standard data acquisition systems
• Operates on a single power supply ranging from 5 V to 30 V

Applications

• Industrial process control temperature monitoring
• HVAC system thermal regulation
• Scientific instrumentation requiring precise temperature measurement

Procurement Notes

Verify the specific suffix 'ARZ' against official Analog Devices documentation to confirm the SOIC-8 package and RoHS compliance status. Confirm availability through authorized distributors as supply may be limited. Ensure the application environment remains within the specified -40 °C to +125 °C operating temperature range to maintain the stated ±4°C accuracy.

Selection Notes

Select this component when a monolithic solution for thermocouple conditioning is required without external linearization circuits. It is suitable for designs needing a wide supply voltage range up to 30 V. Consider the ±4°C accuracy limit for applications where higher precision is not critical. Verify that the SOIC-8 footprint fits the PCB layout constraints.

Part Context

The AD597 series consists of complete thermocouple-to-voltage converter systems. The AD597ARZ specifically denotes the lead-free, RoHS-compliant version in an SOIC-8 surface-mount package. This part eliminates the need for separate cold junction compensation and amplifier stages, simplifying the design of temperature measurement systems.
