General Description
The APA3002 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo Class-D audio power amplifiers capable of producing 9W into 8W (12V) with less than 10% THD+N. The attenuator range of the volume control in the APA3002 is from 36dB (VVOLUME=5V) to -40dB (VVOLUME=0V) with 32 steps. The advantage of internal gain setting can be less components and PCB area. The circuitries of both thermal and the over-current protections are integrated in the APA3002. It protects the chip from being destroyed by over temperature and over current failure.
