Цифровые потенциометры

Цифровые потенциометры позволяют осуществлять регулировку и подстройку электронных схем подобно обычным регулируемым резисторам, реостатам и механическим потенциометрам. Эти компактные компоненты, которые иногда называют RDAC, digital POT или digipot (от digital potentiometer, цифровой потенциометр), могут использоваться для калибровки системных погрешностей или динамической регулировки параметров. Цифровые потенциометры с энергонезависимой памятью позволяют сохранить настройку при отключении питания схемы. Также мы предлагаем однократно программируемые цифровые потенциометры с переплавляемыми соединениями, которые позволяют зафиксировать полученное при подстройке значение.
