Product Summary

The AD590 is a 2-terminal integrated circuit temperature transducer 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 thin-film resistors of the chip is used to calibrate the device to 298.2 μA output at 298.2 K (25℃). The AD590 should be used in any temperature-sensing application below 150℃ in which conventional electrical temperature sensors are currently employed.

Parametrics

AD590 absolute maximum ratings: (1)Forward Voltage ( E+ or E–): 44 V; (2)Reverse Voltage (E+ to E–): -20 V; (3)Breakdown Voltage (Case E+ or E–): ±200 V; (4)Rated Performance Temperature Range: -55℃ to +150℃; (5)Storage Temperature Range: -65℃ to +155℃; (6)Lead Temperature (Soldering, 10 sec): 300℃.

Features

AD590 features: (1)Linear current output: 1 μA/K; (2)Wide temperature range: .55℃ to +150℃; (3)Probe compatible ceramic sensor package; (4)2-terminal device: voltage in/current out; (5)Laser trimmed to ±0.5℃ calibration accuracy (AD590M); (6)Excellent linearity: ±0.3℃ over full range (AD590M); (7)Wide power supply range: 4 V to 30 V; (8)Sensor isolation from case; (9)Low cost.
