The AD5206 is a digitally controlled, 8-bit, six-channel variable potentiometer. Like a mechanical potentiometer, trimmer, or variable resistor, this 256-position device offers a programmable ...

Analog variable frequency filters require the use of variable passive components. The higher the slope of the filter, the greater the number of needed variable passive components. These elements are ...
