General Description

The PAM8007 is a 3W, class-D audio amplifier

with headphone amplifier. Advanced 64-step DC

volume control minimizes external components

a n d

a l l o w s s p e a k e r v o l u m e

c o n t r o l a n d

headphone volume control. It offers low THD+N,

to produce high-quality sound reproduction. The

new filterless architecture allows the device to

drive the speaker

, without 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 PAM8007 is muc h better than

class-AB cousins.

The PAM8007 is available in a SSOP-24 and SOP-

24 package.
