3W FILTERLESS STEREO CLASS-D AUDIO AMPLIFIER WITH DC VOLUME CONTROL
Description
The PAM8603M is a 3W, sterero, 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 numbers of external components, the efficiency of the
PAM8603M is much better than class-AB cousins. It can extend the
battery life thus ideal for portable applications.
The PAM8603M is available in SSOP-24 and SOP-18 packages.
