PAM8610
10W STEREO CLASS-D AUDIO POWER AMPLIFIER WITH DC VOLUME CONTROL
Description
The PAM8610 is a 10W (per channel) stereo Class-D audio amplifier
with DC Volume Control which offers low THD+N (0.1%), low EMI,
and good PSRR thus high-quality sound reproduction. The 32 steps
DC volume control has a +32dB to -75dB range.
Pin Assignments
The PAM8610 runs off of a 7V to 15V supply at much higher
efficiency than competitors’ ICs.
The PAM8610 only requires very few external components,
significantly saving cost and board space.
The PAM8610 is available in a 40pin QFN 6mm*6mm package.
