Ever tear open a potentiometer? If you haven’t, you can still probably guess what’s inside. A streak of resistive material with some kind of contact that moves across it as you rotate the shaft, right ...

I have a Volcano 7 variable speed fan on my Duron 1.2Ghz machine. The fan speed is controlled by a temp. sensor between a 'low' and 'high' speed. The problem is, the crossover point for the two speeds ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

Today, potentiometers dominate the market for linear and rotary path and position sensing. That is not to say that there aren’t other position-measuring systems available on the market (see Table 1), ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...
