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.
