General 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.
