General Description

The  APA0710  is  a  bridged-tied  load  (BTL)  or  singled ended  (SE)  audio  power  a mplifier  developed  es pecially for low-voltage applications where internal speakers and external earphone operati on are  required. The APA0711  is  a  only  BTL   audio  power   amplifier   developed especially  for  low-voltage  applications  where  internal speakers are  required. Operating with a 5V supply ,
