Overview
The AD590JCPZ-R5 is a 2-terminal integrated circuit temperature transducer produced by Analog Devices Inc. This device is designed to produce an output current that is proportional to absolute temperature. It operates as a high impedance, constant current regulator, passing 1 μA/K, and is calibrated to 298.2 μA output at 298.2 K (25°C) through laser trimming of the chip’s thin-film resistors. The AD590 is suitable for temperature-sensing applications below 150°C and is an attractive alternative due to its low cost and the elimination of support circuitry.
