General Description

APA2065 i s a monol i thi c i ntegrated ci rcui t ,  which provides precise  DC  volume control,  and a stereo

bridged audio power  amplifiers capable of  producing 2.7W(2.0W)  into  3W  with  less  than  10%(1.0%)  THD+N. The  attenuator  range  of  the  volume  control  in  AP A2065 is  from  20dB  (DC_Vol=0V)  to  -80dB  (DC_Vol=3.54V) with 32 steps.  The advantage of  internal gain  setting can be less components and PCB area.
