Product details

Class D mono amplifier with integrated headphone driver

The Maxim Integrated MAX9792AETI+ is a Class D audio amplifier from the DirectDrive® series, delivering 3.7W into a 3Ω mono speaker load while simultaneously driving stereo headphones at 180mW per channel into 32Ω. This dual-output architecture suits portable speakers, soundbars, and docking stations where a single IC handles both the main transducer and the headphone jack.

The MAX9792AETI+ is housed in a 28-TQFN (4x4 mm) exposed-pad package for surface-mount assembly.
