RT9101GQW Overview
Description
The RT9101 is a 2.65W, high efficiency Class-D audio amplifier featuring low-resistance internal power MOSFETs and the gain can be set by an external input resistance. The filter free topology eliminates the output filter and reduces the external component count, footprint area, and system costs.
