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 ...

2. A filter circuit is required to smooth the output voltage; there are several tradeoffs in filter-component selection.

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...
