Title: Pls Help me on sunking voltage ic
Post by: muhd85 on November 07, 2010, 04:46:41 PM
Hello im currently builing sunking board, but i manage to get my hands on icl 7660 cpa instead of icl 7660scpa which the layout calls for.

So can i use that 7660cpa?

Nope, you need an scpa.

If it helps, you can also use a TC1044scpa or a Max1044scpa if you can't find the 7660.

To be clear: you can plug in that CPA and it will perform the function, but you will most likely get a whine in the audio path.

The MAX1044 that SB has will work fine. So will this: http://www.mouser.com/ProductDetail/Microchip-Technology/TC1044SCPA/?qs=sGAEpiMZZMuCocSLMfZw%2f9572jYUh8Cw42A68P5EkeI%3d
