General Description

APA2069 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 4W withlessthan 10(1.0)THD+N. The attenuator range of the volumecontrol inAPA2069 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 APA2069, that reduce pops and clicks noise during power up or shutdown mode operation.
