3.2W mono in a 0.96 mm WLP
The MAX98304EWL+T is a Class D audio amplifier delivering 3.2 W into a 4 Ω load from a single mono channel — enough output for a portable Bluetooth speaker or a smartphone earpiece driver where the PCB real estate is the binding constraint.
Supply rail and temperature envelope
Built-in depop circuitry suppresses the turn-on thump that otherwise couples through the speaker into the user's ear. Differential inputs reject ground noise picked up on the audio trace between the codec and the amp — a common headache in mixed-signal boards where the digital return current shares the ground plane.
