Class D topology keeps efficiency above 85% at full output, so the 36-TQFN exposed-pad package can dissipate the heat without a large heatsink in many designs. Supply range is 8V to 28V, giving flexibility for single-rail or regulated supplies in powered speakers, soundbars, or industrial audio systems. ## Package and mounting Housed in a 36-TQFN exposed pad (6x6 mm body). The exposed pad must be soldered to a thermal land on the PCB — the datasheet's recommended footprint and via pattern are critical for heat transfer. Surface-mount assembly, supplied in Tape & Reel (TR) or Cut Tape (CT) options.","metaTitle":"MAX98400AETX+T Class D Audio Amp, 20W x 2 @ 8Ω, 36-TQFN","metaDescription":"MAX98400AETX+T is an active Class D stereo amplifier delivering 20W per channel into 8Ω.
