2007-04-24 3:14 am. #1. 2007-04-24 3:14 am. #1. I'm doing a variable power supply which uses a 5k pot to vary the voltage, but i'd like to replace the regular pot with a "digital" pot (using buttons and an IC instead of a pot). Does anyone have an schematic to do this? cause i haven't seen any 5k pot ic of that kind.
Digital potentiometer for volume control | diyAudio

we may look at the DS1882 digital potentiometer (doesn't have any opamps inside, just a analog signal potentiometer which is controlled digitally via i2c). it needs to be connected to a very high input impedance stage (may be a buffer - discreet/opamp). and also takes care of zero crossing issue and also needs dual supply upto +/-7v. jan.didden

I think that digital pot is at least as good as the best mechanical pots, if not better. It's nice that mlloyd1 informed us that there are examples from Maxim and Muse that do not have even internal opamp. The biggest obstacle for amateurs is programing of MCU and display interface. But the sound is excellent. Another excellent digital pot is ...

A potentiometer, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.

Abstract: Digital potentiometers (pots) offer advantages for audio volume (gain) control applications and can replace bulky mechanical pots, especially in handheld portable devices such as MP3 players, PDAs, cell phones, mobile Internet devices, or stereo AM/FM radios. This document describes the types of digital pots available for audio control such as logarithmic …
