Class-D amps are cool, but Wafer Packaging? You will need a microscope to solder it, the pins are only 0.5mm apart! :shock:
i agree maxim makes some similar stuffi got all excited about and then i was like arghhhhhhhhhhhhhhhhhhhhh can't see daylight between these pins..but i manged to get these working there WG so i am sure you can get yours going.. :)
hey.. you get the op amp alerts from TI too.. you must have ordered samples ;p

Me too. I got the same alert. I love it. I get free samples, then I get email alerts on new products so I can get samples of them!
TI helps put the stomp into stompbox.

HAHAHAHAHAHA
Can you guys explain this chip to me? How does the shutdown work?
I'm sure someone makes a socket for these that will have long leads for testing purposes.

Folks,
May I suggest you forget TI and Maxim, and check out a really good Class D chip for our purposes that will take a 9 volt battery?
The MPS MP7501 chip - in a 8-pin SOIC package. Efficent and OOMPH!
Think onboard string drivers. I am... :)
you do realize that class d amplifiers by definition.. although efficient actually require a large input signal over the other classes of amplifiers..
thats why you dont' see them in too many things.
sure they are in cellphones..
they are also in radio towers...
it isn't too hard to get 100,000 watts when you are driving it with 10,000 watts.
not trying to stomp on the idea.. but you will probally need somehting around a lm386 or so to drive it efficiently... i know i am only getting about 1.2 watts from mine when i drive it with a single transistor.
i use it as a a pedal. where as i get the full 2.5 watts from the same setup with my lm380
but then again theres also the effeciency factor and the fact that it only needs like what 2.7 to 5.2 volts.. so maybe we can kick some extra juice out of it with 9v
Ansil,
That is the beauty of the MP7501 - it will put out 5 watts with 12 volts, a tad less with 9 depending on the load impedance. It put out every bit as much power as a LM380 - just more efficently. An op amp will drive it just fine. Haven't tried it for an overdrive, though :( :idea: :lol:
Forget TI chips with bumps, get a chip you can actually build into something without a robot factory and ultra-thin foil super-fine-line PCBs.
hmm interesting. :D
Thanks for the heads-up on the MP7501 Mr. Coffee! :D 8)
Now my next question is..... how does it sound when overdriven? :twisted:
Take care,

Peter,
Probably not great - haven't tried it. But iit IS real efficent if you are trying to put out some power and not spend your life changing batteries or worrying whether your whatever is going to crap out if you play 3 songs instead of 2. :wink:
