应用功能： Low Power, Low Cost2.5 V Reference The AD680 is a bandgap voltage reference which provides afixed 2.5 V output from inputs between 4.5 V and 36 V. Thearchitecture of the AD680 enables the reference tobe operatedat a very low quiescent current while still realizing excellent dc characteristics and noise performance. Trimming of the highstability thin-film resistors is performed for initial accuracy andtemperature coefficient, resulting in low errors over temperature.
