PAM8603MNHR

PAM8603MNHR is a stereo, class-D audio amplifier with DC 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 directly, requiring no low-pass output filters, which saves the system cost and PCB area. With the same number of external components, the efficiency of the PAM8603M is much better than its class-AB cousins. It can extend the battery life, thus ideal for portable applications. Applications include LCD monitors/TV projectors, notebook computers, portable speakers, portable DVD players, game machines, cellular phones/speaker phones.
