MAX4409, Stereo Headphone Amplifier

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.
