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 ...

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 ...

Potentiometers, rheostats, and trimmers are adjustable resistors used to measure or divide voltages in order to protect or control circuits. The terminology surrounding potentiometers and related ...

Digital potentiometers are digitally controlled variable resistors that can be used in place of their functionally equivalent mechanical counterparts. While digital potentiometers offer comparable ...

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 ...

If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works, that ...
