PAM8007
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.
