single push volume pot, volume up/down via a button.

dragonxwas · 1st June 2011, 05:18 PM

Well, My first post here,I wanted some help from you guys,

you see I want to make a cmoy amp,

now I have sorted out all the parts and I am using small lithium packs in series-parallel mode coming to around +-6v for the opamp and have figured out everything else,

Now instead of using a volume pot. I wanted to use something that allows me to increase/decrease volume at a push of a switch or two..

Like you have on the television sets press + and volume increases and press - and it goes down..

Well I've tried on the web and all I ended up was with MAXIM chips, such as 5486 and similar types, I have problems sourcing MAXIM chips in my country, so I am looking for alternatives.. Other than that is there any other way this could be done ?

If you want to use the MAXIM part, it was discussed in another thread here on the forum complete with pictures drawings ect.
MAX5486- digi pot help!

I see that there are none in stock at DigiKey. Try other supliers like Mouser or Farnel

I checked with my local retailers about maxim parts, they have no idea about it and I seem to be unlucky at online purchases.. so...seeking different ways..
