The AD590KH from Analog Devices is a versatile 2-terminal integrated circuit temperature transducer. It outputs a current that is directly proportional to absolute temperature, specifically 1 μA/K. This device operates reliably over a wide temperature range of -55°C to +150°C and supports a broad power supply range from 4V to 30V.
Designed for ease of use, the AD590KH eliminates the need for external linearization circuitry, precision voltage amplifiers, or resistance measuring circuits. Its high impedance current output makes it suitable for remote sensing applications, as it is insensitive to voltage drops over long lines. The device is available in a probe-compatible ceramic sensor package, specifically the TO-52 form factor for through-hole mounting.
Applications for the AD590KH include general temperature measurement, temperature compensation or correction of discrete components, biasing proportional to absolute temperature, flow rate measurement, and fluid level detection. Its inherent low cost and elimination of support circuitry make it an attractive alternative for many temperature measurement situations.
