APA2068 Overview
APA2068 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.8W) into 4Ω with less than 10% (1.0%) THD+N. The attenuator range of the volume control in APA2068 is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. The advantage of internal gain setting can be less ponents and PCB area.
