The MAX97220CETE+T: The Class AB output stage keeps crossover distortion below the noise floor at low listening levels, which matters more for IEMs than the peak power number suggests.
The 0.5 mm pitch QFN demands a solder-paste stencil aperture that matches the pad geometry in the land pattern; the datasheet's recommended footprint is the starting point, not the end of the discussion.
125 mW per channel into a 32 Ω load, stereo. That is the rated maximum output power per channel — the actual level before clipping depends on the supply voltage and the headroom the DirectDrive charge pump provides.
