The AD590KF is a 2-terminal integrated circuit temperature transducer manufactured by Analog Devices. It provides a linear current output of 1 μA/K, making it proportional to absolute temperature. This device operates over a wide temperature range of -55°C to +150°C and is suitable for various temperature sensing applications.
The AD590KF functions as a high impedance, constant current regulator for supply voltages between 4 V and 30 V. It is laser trimmed for calibration accuracy and offers excellent linearity over its full operating range. The sensor is probe-compatible and available in a 3-pin TO-52 package, suitable for through-hole mounting.
This temperature transducer eliminates the need for linearization circuitry, precision voltage amplifiers, or resistance measuring circuitry, making it a cost-effective alternative for many temperature measurement situations. Its current output makes it insensitive to voltage drops over long lines, ideal for remote sensing applications.
