The AD590KR is a highly precise, monolithic integrated circuit temperature transducer from Analog Devices Inc. that provides an output current proportional to absolute temperature. Designed for high-precision applications, the AD590KR is an ideal choice for temperature measurement and control systems, being both reliable and easy to use.

This temperature transducer operates by producing a current output of 1µA/K, ensuring a linear response over a wide temperature range. The device is calibrated in Kelvin, meaning the output current is directly proportional to the absolute temperature with no additional scaling required. The AD590KR is suitable for temperatures ranging from -55°C to +150°C, providing a versatile solution for various environments.

The two-terminal IC temperature transducer is packaged in a robust metal can (TO-52), ensuring durability and stable performance even under harsh conditions. It can be easily integrated into systems with a simple current measuring interface, making it a convenient option for engineers and designers looking for a straightforward temperature monitoring solution.

The AD590KR's high-impedance current output allows for minimal self-heating, less than 0.1°C in still air, which is a critical feature for maintaining accuracy in temperature measurements. Moreover, the device does not require any external calibration or trimming to provide typical accuracies of ±0.5°C at room temperature and ±1°C over a full -55°C to +150°C temperature range.

Applications for the AD590KR are diverse and include electronic equipment temperature monitoring, environmental control systems, process control systems, and temperature compensation circuits. Its ease of use, combined with its high level of precision, makes the AD590KR a reliable component for any temperature-sensitive application.

Analog Devices Inc. is renowned for its high-quality products, and the AD590KR temperature transducer is no exception. It stands as a testament to the company's commitment to providing innovative, precise, and reliable solutions for the industry's temperature measurement needs.
