The AD590JR is an integrated circuit that can be used as a temperature sensor in many applications. It provides a linear output voltage that is proportional to the measured temperature and can be read directly or used in combination with an amplifier to produce a variety of temperature-related signals. This makes the AD590JR a very popular temperature sensor in controlling, measuring, and regulating temperature with precise accuracy.

The AD590JR is based on the integrated bridge circuit principle and works by using an internal bridge of silicon transistors to produce a stable reference voltage. This reference voltage output is proportional to the average of two current sources, with a ratio between the two sources dependent upon temperature. This enables the reference voltage to change proportionally to temperature, leading to the linear analog output voltage that is proportional to the temperature.

The operating temperature range of the device is -40 to +125°C, which makes it suitable for a wide variety of temperature sensing applications. Typical applications of the AD590JR include temperature probes, automotive engine sensors, thermocouples, and heaters. Its wide operating range makes it suitable for diverse environments, from cryogenic to very hot, with excellent accuracy. Additionally, the device is extremely robust with short-circuit protection and high immunity to environmental disturbances, making it perfect for demanding environments.

The AD590JR produces a linear output voltage of 10 mV/°C and can be used for low-cost, precise temperature sensing. It is available in three different packages: a 14-pin dual-in-line package (PDIP); a 9-pin dual-in-line package (PDIP) and a surface mount package (SMP). The device offers a wide range of features, including low voltage operation, low offset and drift, excellent linearity, and a wide temperature range.

The AD590JR is an ideal choice for many applications which require precise temperature sensing. It provides accurate, linear analog output voltage proportional to the temperature, in a wide temperature range. Its robustness and small size makes it a great choice for diverse temperature sensing applications in many industries.
