PAM8010
3W STEREO CLASS-D with
DC VOLUME, HEADPHONE and POWER LIMIT
Description
The PAM8010 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.
Integrated power limit technology which suppresses the output signal
clip automatically due to the over level input signal. It offers low
THD+N to produce high-quality sound reproduction.
PAM8010 has an additional noise reduction circuit which achieves
12dB nosie attenuation. This circuit may help eliminate external
filtering, thereby saving the board space and component cost.
The PAM8010 features SCP (short circuit protection), OTP and
thermal shutdown.
The PAM8010 is available in SSOP-24 and SOP-24 package.
