80mW, DirectDrive, Stereo Headphone Amplifier with Common-Mode Sense
General Description
The MAX4409 stereo headphone amplifier combines Maxim’s DirectDrive architecture and a common-mode 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 r...
