Analog Devices Inc. AD595AQZ Thermocouple Amplifier

The AD595AQZ is a high-precision thermocouple amplifier integrated circuit brought to you by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This device is specifically designed to interpret the low voltage signals generated by a type K thermocouple, which is widely used for its ability to measure a broad range of temperatures.

The AD595AQZ simplifies the process of temperature measurement by including all the necessary components for thermocouple signal conditioning within a single monolithic chip. This includes an ice point reference, a cold junction compensator, and a high gain amplifier. The output is a linearized voltage directly proportional to the temperature, eliminating the need for complex calculations or external calibration.

With its robust design, the AD595AQZ is capable of providing accurate temperature readings over a wide range, typically from -55°C to +125°C, with a sensitivity of approximately 10mV/°C. The device is pre-calibrated by Analog Devices to ensure high accuracy without the need for further adjustment, making it a reliable choice for precision temperature monitoring in industrial control systems, HVAC, and scientific instrumentation.

Key features of the AD595AQZ include:

• Directly calibrated in °C for type K thermocouples
• Linear 10mV/°C scale factor
• 0.5°C accuracy guaranteeable at room temperature
• Operates from single-ended power supply (5V to 15V)
• Built-in cold junction compensation
• High impedance differential input
• Low power consumption
• Thermocouple failure alarm

The AD595AQZ comes in a 14-lead ceramic dual in-line package (CERDIP) for ease of integration into your system. Its robust packaging and high-quality construction ensure reliable operation even in harsh environmental conditions.

Whether you're developing a sophisticated temperature control system or need reliable temperature readings for process monitoring, the AD595AQZ from Analog Devices Inc. stands out as a top-tier solution that combines convenience, precision, and reliability in one compact package.
