How would this be for an amp?

soundNERD · 28th September 2004, 12:30 AM

I was wondering if somebody has tried an OPA544 as an audio amp.

It runs off of up to 70V and puts out 2A min current.

Would this chip be a good choice for an amp? Would it deliver enough power to drive most speakers?

here is the info on it:

I ordered some yesterday, should I just try it and see how it works??
