A Product Line of Diodes Incorporated PAM8008 3W STEREO CLASS-D with DC VOLUME, POWER LIMIT and ANTI-SATURATION Description Pin Assignments 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. Applications The PAM8008 is available in SOP-16L package.
