Maxim's headphone amplifier ICs deliver industry-leading audio quality and performance. Our DirectDrive® technology improves on conventional single-supply headphone amps with reduced solution size, cost savings, and enhanced audio quality.

All Headphone Amplifier ICs 

DirectDrive Headphone Amplifiers

DirectDrive headphone amplifiers eliminate the need for a DC-blocking capacitor required by conventional headphone amps, resulting in reduced distortion, significantly less click-and-pop, better bass performance, and savings in solution size and cost.

Maxim's Class H headphone amplifier ICs provide higher efficiency than the closest competitive Class G amplifiers. Our dual-mode DirectDrive II Class H headphone amplifiers save power by switching between two supply voltages. This technology renders a continuous signal without the glitches seen in Class G amplifiers.
