The Class AB output stage keeps crossover distortion low without the quiescent current penalty of pure Class A, making it a fit for battery-powered audio where efficiency and sound quality both matter. Supply range spans 2.3 V to 5.5 V, so it runs directly from a single Li-ion cell (3.0-4.2 V) or a regulated 3.3 V / 5 V rail. The -40°C to +85°C operating temperature covers consumer portable gear and extends into industrial ambient environments where the enclosure sees moderate heat. ## Package and board integration Housed in a 9-ball UCSP (1.52 × 1.52 mm), the MAX4368EBL+ is one of the smallest audio amplifiers in its power class. The 0.5 mm ball pitch and 1.52 mm body mean the entire amplifier fits under a finger nail — critical for true wireless earbuds, hearing aids, or wearable audio modules where PCB real estate is the tightest constraint. Surface-mount assembly with the CSPBGA footprint requires standard SMT reflow; the small body means the thermal pad (if present) is minimal, so the power dissipation limit is set by the board copper rather than the package alone. The bulk packaging suggests tray or tube delivery — verify reel availability if your pick-and-place line expects tape-and-reel. ## Lifecycle and sourcing reality No pin-compatible second source is listed on the official record — if you need an alternative, the MAX4367 is the natural cross-reference to evaluate, though pin compatibility should be verified against the respective datasheets.","metaTitle":"MAX4368EBL+ Class AB Audio Amp, 330mW, 9-UCSP","metaDescription":"MAX4368EBL+ Class AB mono audio amplifier, 330mW into 16Ω, 2.3-5.5V supply, 9-UCSP 1.52mm package.
