General Description:
APA2065 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.7W(2.0W) into 3W withless than10%(1.0%)THD+N. The attenuatorrange of the volumecontrol inAPA2065 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. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in APA2065, …
