MAX9721
Overview
The MAX9721 fixed-gain, stereo headphone amplifier is ideal for portable equipment where board space is at a premium. The MAX9721 uses a unique, patented DirectDrive architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height.
