Single switch digital potentiometer


Posted on Jun 22, 2012

The control of electronic potentiometers in most today`s applications comes from controller-generated signals. However, a significant number of applications exist that require adjustments using manual, front-panel controls. The circuit in Figure 1 uses one IC, one switch, and 10 discrete components. It implements the interface of a single DPDT, momentary-contact rocker switch to a DPP (digitally programmable potentiometer). The Catalyst DPP has a three-wire increment/decrement interface.



The traditional way to implement the front-panel controls for potentiometers with this type of interface is to use two single-pole, single-throw switches. Switch S1 reduces the front-panel hardware by half. The action of the switch is natural for the cont
