Характеристики

AD680ARZ, Маломощный источник опорного напряжения, 2.5В …The AD680 series low-power band gap Voltage Reference provides a fixed 2.5V output from inputs between 4.5V and 36V. The architecture of the AD680 enables the reference to be operated at a very low quiescent current while still realizing excellent DC characteristics and noise performance. Trimming of the high stability thin-film resistors is performed for initial accuracy and temperature coefficient, resulting in low errors over temperature. The precision DC characteristics of the AD680 make it ideal for use as a reference for DACs that require an external precision reference. The device is also ideal for ADCs and, in general, can offer better performance than the standard on-chip references. Based upon its low quiescent current, which rivals that of many incomplete references, the AD680 is recommended for low power applications, such as hand-held and battery-operated equipment.
