The AD590KF from Analog Devices is a versatile 2-terminal integrated circuit temperature transducer designed for accurate temperature sensing. It outputs a current that is directly proportional to absolute temperature, with a linear output of 1 μA/K. This device is suitable for applications requiring temperature measurement from -55°C to +150°C.
The AD590KF operates with a wide power supply range of 4V to 30V, acting as a high impedance, constant current regulator. It is laser trimmed for calibration accuracy and offers excellent linearity over its full operating range. The sensor is probe-compatible and comes in a 2-lead ceramic flatpack, suitable for surface mount applications.
This temperature transducer eliminates the need for external linearization circuitry, precision voltage amplifiers, or resistance measuring circuits, making it an attractive and cost-effective solution for various temperature measurement situations. Its high impedance current output makes it insensitive to voltage drops over long lines, ideal for remote sensing applications.
Key specifications include an operating temperature range of -55°C to +125°C, with a sensing temperature range of -55°C to +150°C. The accuracy is ±2.5°C at 25°C, and it supports a supply voltage from 4V to 30V. The output type is analog current.
