The Maxim Integrated MAX98400AETX+ is a 2-channel (stereo) Class D audio amplifier rated for 20W per channel into an 8Ω load. It runs on an 8V to 28V supply rail, which gives you flexibility across 12V automotive audio, 24V industrial PA systems, and 18V portable battery-powered speakers. The 36-TQFN (6x6) package with exposed pad keeps the heat managed without a big heatsink — useful when board space is tight.
