The 4.5V minimum supply means it operates from a single lithium-ion cell or a regulated 5V rail. The shutdown feature (part of the feature set) allows the output stage to be disabled, reducing quiescent current draw when the audio path is idle — useful for battery-powered designs where standby power matters. ## Package and board integration Surface-mount mounting and tube packaging suit both prototype hand-assembly and medium-volume reflow lines. The supplier device package is 14-TSSOP, so the land pattern is consistent across the Analog Devices portfolio. ## Lifecycle and compliance status ROHS3 compliant, with no known obsolescence notices.","metaTitle":"MAX9728AEUD+ Analog Devices Class AB Stereo Headphone Amp","metaDescription":"MAX9728AEUD+ Analog Devices Class AB stereo headphone amplifier, 60mW x 2 into 32Ω, 14-TSSOP.
