FoCUSens FST Series 2-Terminal IC Temperature Transducer 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 pA/K. Laser trimming of the chip’s thin-film resistors is used to calibrate the device to 298.2 pA output at 298.2 K (25°C). Typical Applications - Refrigerator, - Air conditioner, - Granary, - Ice house, - Industrial equipment Features - Wide power supply range: 4 V to 30 V - Linear current output: 1 pA/K - Wide temperature range: -55°C to +150°C - 2-terminal device: voltage in/current out - Excellent linearity: ±0.3°C over full range (AD590M) Technical Data Parameter Power Supply Sensor DA590J Output Current @ 25°C Temperature Coefficient Response Output Reverse Bias Leakage Current(2) Note : (1) 25°C and VS = 5 V, unless otherwise noted. (2) Leakage current doubles every 10°C. (3) Detailed specification see Analog Devices AD590 Datasheet. FST V1.0/Modification rights reserved www.focusens.com
