description
the ema2016 is a stereo, filter-less class-d audio amplifier. operating with 5.0v loudspeaker driver supply, it can deliver 1.5w/ch output power into 8ω?loudspeaker and 2.5w/ch output power into 4ω?loudspeaker within 10% thd+n.
the ema2016 packaged as sop 16l is a stereo audio amplifier with high efficiency and proper thermal resistance, which leads to longer battery life and less heat sink requirement. it’s suitable for the notebook computer, and portable multimedia devices. ema2016 with the independent shut-down control for left or right channel, that’s a better solution for low cost class-d system.
