FILTERLESS 3W CLASS-D STEREO AUDIO AMPLIFIER

with DC VOLUME CONTROL and HEADPHONE OUTPUT

Description

The PAM8007 is a 3W, Class-D audio amplifier with headphone

amplifier. Advanced 64-Step DC volume control minimizes external

components and allows speaker volume control and 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 directly, 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 much better than class-AB cousins. It can extend the

battery life thus be ideal for portable applications.

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