25 mW per channel into 16 Ω — the output power that drives earbuds and IEMs
The MAX9725CETC: Rated 25 mW per channel into a 16 Ω load, this Class AB amplifier delivers enough swing for consumer earbuds and in-ear monitors without the crossover distortion typical of lower-bias topologies.
DirectDrive — no DC-blocking output capacitors
The DirectDrive architecture generates a negative supply rail internally, centering the output at ground so no large DC-blocking capacitors are needed on the headphone outputs. This saves board area and eliminates the low-frequency roll-off and phase shift that electrolytic output caps introduce.
