Цифровые потенциометры

Линейка цифровых потенциометров компании Analog Devices обладает превосходными характеристиками в широком диапазоне промышленных температур. Эти компактные устройства, иногда называемые digital pot, RDAC или digiPOT, могут использоваться для калибровки системных погрешностей или динамической регулировки параметров. Такие цифровые потенциометры, как AD5123 и AD5143, имеют энергонезависимую память, 128 / 256 положений регулировки, малое допускаемое отклонение от номинального сопротивления и низкий температурный коэффициент, что упрощает создание приложений с разомкнутым контуром обратной связи или приложений, где необходимо согласование значений допуска.
