Features
General Description
The APA2603 is a stereo, high efficiency, filter-free ClassD audio amplifier available in SOP-16P and DIP-16 packages. The APA2603 provides the precise DC volume control, the gain range is from -80dB (V VOLUME =5V) to +20dB (VVOLUME=0V) with 64 steps precise control. It’ s easy to get the suitable amplifier’ s gain with the 64 steps gain setting. The filter-free architecture eliminates the output filters pared to the traditional Class-D audio amplifier and reduces the external ponent counts and the ponents high. Besides, it can save the PCB space, system cost, and simplify the...
