General 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 suppress
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 achieve12dB nosie attenuation . This circuit
may help eliminate external filtering, thereby
saving the board space and components cost.
T h e PA M 8 0 1 0 f e a t u r e s S C P ( s h o r t c i r c u i t
protection), OTP and thermal shutdown.
The PAM8010 is available in SSOP-24 and SOP-
24 package.
