3W STEREO CLASS-D with DC VOLUME,

POWER LIMIT and ANTI-SATURATION

Description

The PAM8008 is a 3W, Class-D audio amplifier. Advanced 64-step

DC volume control minimizes external components and allows

speaker volume control.

Integrated power limit technology which suppress the output signal

clip automatically due to the over level input signal. It offers low

THD+N and protect speaker.

Integrated anti-saturation technology which suppress the output

signal clip automatically when supply voltage changes. It offers low

THD+N, to produce high-quality sound reproduction.

PAM8008 has an additional noise reduction circuit which achieves

6dB noise attenuation. This circuit may help eliminate external

filtering, thereby saving the board space and components cost.

The PAM8008 features SCP (short circuit protection), OTP and

thermal shutdown.

The PAM8008 is available in SOP-16L package.
