The output form9 of the integrated temperature sensor is divided into two kinds voltage exporting and electric current outputs. The sensitivity of the voltage outputting type is generally 10mV/K, Temperature 0 Degrees Centigrade are exported hour 0 ,Temperature 25 Degrees Centigrade are exported hour . The sensitivity of the outputting type of the electric current is generally 1 m A/K . AD590 It is the single integrated temperature sensing electric current source of both ends where . simulation device Company produces. Its main characteristic is as follows: (1) flow through device electric current ( m A )Mean the reading of thermodynamics temperature (turns on gently ) of living in environment of the device. (2) AD590 Examine warm range 55 Degrees Centigrade +150 Degrees Centigrade. (3) AD590 Power voltage range 4V 30V . The voltage of the power can be here 4V~6V The range changes, electric current Change 1 m A ,In other words temperature changes 1K . AD590 Can bear 44V To voltage sum 20V Reverse voltage, therefore the transposition of the device will not be damaged either. (4) the resistance of output is 710M W . (5)the precision is high. AD590 Own in mon I J K L M Five shelves, among them M The shelf is the highest in precision, here 55 Degrees Centigrade +150 In one degrees Centigrade of ranges, the nonlinear error is 177。 Degrees Centigrade. the application circuit basically Pursue 1 ( a ) AD590 Encapsulation form, pursue 1 ( b ) AD590 Used for measuring using the circuit basically of thermodynamics temperature. Because flow through AD590 Electric current in direct proportion to thermodynamics temperature, look on as resistance R 1 With the electric potential device R 2 Resistance sum 1k W Hour, output the voltage VO The change which is up to temperature is 1mV/K . But because AD590 Gain by deviation of having, resistance too it have error of, so should adjust to circuit. The method to adjust is: One AD590 Put in the frozen water mixture, the electric potential adjusting device R 2 ,Make VO = . Or under the room temperature (25 Degrees Centigrade )Pursue 1 ( a ) AD590 Encapsulation form, pursue 1 ( b ) AD590 Used for measuring using the circuit basically of thermodynamics temperature.
