Product Summary
The AD590MH/883B is a 2-terminal integrated circuit temperature trans-ducer that produces an output current proportional to absolute temperature. For supply voltages between 4 V and 30 V, the device acts as a high impedance, constant current regulator passing 1 μA/K. Laser trimming of the chip’s thin-film resistors is used to calibrate the device to 298.2 μA output at 298.2 K (25℃). The AD590MH/883B should be used in any temperature-sensing application below 150℃ in which conventional electrical temperature sensors are currently employed.
