Amazing what you can find with Google.

I did Google, and received about what you did but that does not begin to answer
the question.

Call On Semiconductor's Marketing department, and ask them. They're in
that market; they should be in a position to know.

Do you have 600 Euros? You can download a hearing aid market report
from these folks:

http://www.researchandmarkets.com/re...al_hearing_aid

It lists the major players in the hearing aid industry. You could call
them, and ask where they source their ICs, how many they buy per year,
etc.

Realize that sci.electronics.repair is not
