It offers low THD+N,allowing it to produce high-quality sound reproduction .The new filterless architecture allows the device to drive the speaker directly without needing low-pass output filters which will save 30% system cost and 75% PCB area. With the same numbers of external components .the efficiency of the MD3303 is much better than class-ab cousins, It can extend the battery life ideal for portable applications. The MD3303 is available in SSOP-24 and SOP-16 package.
