19-2842; Rev 0; 4/03 .. 80mW, DirectDrive, Stereo Headphone Amplifier with mon-Mode Sense General Description The MAX4409 stereo headphone amplifier bines Maxim’s DirectDrive architecture and a mon-mode sense input, which allows the amplifier to reject mon-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 ponent height. The mon-mode voltage sensing corrects for any difference between SGND of the amplifier and the headphone...
