That output level is enough to drive consumer earbuds or low-impedance headphones to comfortable listening volume from a single Li-Ion cell, since the supply range spans 2V to 5.5V. ## Package and supply integration Housed in a 10-VSSOP (3.00 mm wide MSOP) package, the LM4929MM fits compact portable audio PCBs where board area is tight. The 2V to 5.5V supply rail means it runs directly from a single lithium cell without an extra regulator.","metaTitle":"LM4929MM Texas Instruments Boomer Audio Amp, 80mW x 2","metaDescription":"Texas Instruments LM4929MM Boomer Class AB stereo headphone amp, 80mW x 2 into 16 Ohm, 2-5.5V supply, 10-VSSOP.
