Audio amplifier

   Has anybody thought of using something like the
   MAX9710 to get some reasonable power out of the

   To my suprise, there seems to be no external amp
   in the recorder for the headphones and I've connected
   small passiv sony speakers for a walkman (8Ohm!!)
   directly to the MAS 3587F for hours.. :-)

   The above IC delivers up to 2x2W_at_4Ohm, doesn't need
   large capacitors, has a rather small footprint, needs
   only few external components and draws typically 12mA
   for itself.

   Better ideas to improve the output power?
