DESCRIPTION
The  SC7422  is  a  class  AB  power  amplifier  which  designed  for dual audio purpose. It can deliver 2W × 2 power output to the 4ȍ load in the 5V operation voltage. Total harmonic distortion is lower than 0.03%. The output  mode  can  be  switched  between  the  SE  and  BTL  mode.  The volume also can be changed by a 32 steps volume controller. Moreover, the  SC7422  requires  a  few  extra  components  in  the  application.  It  is suitable for small or portable products.
