PAM8008
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.
Features
3W Output at 10% THD with a 4 Load and 5V Power Supply
2.4W Output at 1% THD with a 4 Load and 5V Power Supply
