PAM8008DR

PAM8008DR is a class-D audio amplifier. Advanced 64-step DC volume control minimizes external components and allows speaker volume control. Integrated power limit technology that suppresses the output signal clip automatically due to the over-level input signal. It offers low THD+N and protects the speaker. Integrated anti-saturation technology that suppresses the output signal clip automatically when the 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 board space and component cost. The PAM8008 features SCP (short circuit protection), OTP, and thermal shutdown. Applications include LCD monitors/TV projectors, notebook/all-in-one computers, portable speakers, portable DVD players, game machines.
