　　General Description The PAM8803 is a 3W， class-D audio amplifier with 64-step digital volume control. It offers low THD+N， allowing it to produce high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker ， 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 PAM8803 is much better than class-AB cousins. The PAM8803 is available in a SSOP-24 package.
