80mW, DirectDrive, Stereo Headphone Amplifier with Common-Mode Sense
General Description
The MAX4409 stereo headphone amplifier combines Maxim's DirectDriveTM architecture and a commonmode sense input, which allows the amplifier to reject common-mode noise.

Conventional headphone amplifiers require a bulky DC-blocking capacitor between the headphone and the amplifier. DirectDrive produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, which saves cost, board space, and component height. The common-mode voltage sensing corrects for any difference between SGND of the amplifier and the headphone return. This feature minimizes ground-loop noise when the HP socket is used as a line out connection to other grounded equipment, for example, a PC connected to a home hi-fi system. The MAX4409 draws only 5mA of supply current, delivers up to 80mW per channel into a 16 load, and has a low 0.002% THD+N. A high 86dB powe
