Analog Devices AD2040

The AD2040 is a low-cost 3 digit temperature indicator. Its output is a current (lJ.LA per K) linearly proportional to absolute temperature, thus eliminating the need for costly linearization and cold junction compensation. Based on the highly successful AD2026 low-cost DPM and designed O to be used in conjunction with Analog Devices' AC2626 genL eral purpose probe or the AD590 temperature transducer, the AD2040 is available in both 5V logic-powered, or ac line- E powered versions.

GENERAL DESCRIPTION

S TE The 5VpoweredAD204D-12 reads out directly in °c, of, oR transducer. Due to the AD590's high impedance current output, it is insensitive to voltage drops over long lines thus enabling remote monitoring with no need for costly transmitters or special wire. or K. A precision voltage reference, resistor network, and span and zero adjusts, needed to implement display of the different temperature scales, are all self-contained. User selectable de- AD590 4 R. gree readout, as well as all other connections, i.e., +5V power HI R1 IN and sensor or probe interface, are all made via a terminal block on the rear.
