AD590JH - Precision IC Temperature Transducer

The AD590JH is a highly accurate IC temperature transducer from Analog Devices Inc. that converts temperature directly into a proportional current with exceptional precision. Designed to simplify the process of temperature sensing in a wide range of applications, this two-terminal integrated circuit temperature transducer provides an output current directly proportional to absolute temperature.

With its robust design, the AD590JH is suitable for environments that require precise temperature monitoring and control. It operates over a temperature range of -55°C to +150°C, ensuring reliable performance in both commercial and industrial settings. The device is characterized for operation from -55°C to +150°C, providing a current output of 1µA/K, which means that for every degree Kelvin change in temperature, the output current changes by 1µA.

The simplicity of the AD590JH's design allows it to be easily interfaced with a wide variety of hardware. The linear current output can be converted to a voltage with a simple resistor, making it compatible with most analog-to-digital converters (ADCs) for digital readouts. Additionally, the device can be easily multiplexed, providing flexibility for systems that require temperature data from multiple points.

Key features of the AD590JH include:

• Linear current output: 1µA/K
• Wide temperature range: -55°C to +150°C
• Excellent linearity: ±0.3°C accuracy at room temperature
• Wide power supply range: 4V to 30V
• Minimal self-heating effects
• Stable with capacitive loads

Applications for the AD590JH are diverse and include environmental control systems, temperature monitoring inside electronic equipment, process control, and temperature compensation for other electronic components. Its rugged, hermetically sealed package (TO-52 can) ensures durability and long-term stability, making the AD590JH a reliable choice for demanding applications.

Whether you're developing a sophisticated climate control system or simply need to monitor temperature within a circuit, the AD590JH from Analog Devices Inc. offers a straightforward and accurate solution for your temperature sensing needs.
