Simple, SIMPLE Digital volume control

[-_nando-_]

Hi !!

I already searched around the forum, but I only find complex controls, with LCD, or high sonic quality ones etc.

Would be very nice to have a volume control with button UP and DOWN, nothing else, without display or anything. This is for a portable headphone amp that aways fall on the floor and the pot fail...

Do you know where I can find something simple like this? It's just like a a "pot replacement".


I'll be very glad if anyone share it.


Thanks !!

This approach is using their push-button potentiometer. Keep in mind that a digital pot scheme will be more complicated than a simple potentiometer. All digital pots need their separate power supply requirements, and most of them must be interfaced via a microcontroller (SPI), although a couple (like the one mentioned in the above appnote) can still be made push-button.
