FILTERLESS 3W CLASS-D STEREO AUDIO AMPLIFIER
Description
The PAM8004 is a 3Wm Class-D audio amplifier. It offers low
THD+N, allowing it to achieve high quality sound reproduction. The
new filterless architecture allows the device to drive the speaker
directly, requiring no low-pass output filters, in order to save system
cost and PCB area.
With the same numbers of external components, the efficiency of the
PAM8004 is much better than that of Class-AB cousins. It can extend
the battery life, ideal for portable applications
The PAM8004 is available in SOP-16L package.
