General Description
The PAM8606 is 6W (per channel), stereo class-
D audio amplifier with DC Volume Control which
offers low THD+N (0.1%), low EMI, and good
PSRR, allowing it to produce high-quality sound
reproduction. The 32 steps DC volume control
has a +32dB to -75dB range.
The PAM8606 runs off of a 7.0V to 13.5V supply
a t m u c h h i g h e r e ff i c i e n c y t h a n c l a s s - A B
amplifier.
The PAM8606 only requires minimal number of
external components, resulting in significant
cost and board space savings.
The PAM8606 is available in a 48pin TQFP(E-
PAD) 7mm*7mm package .
