General 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.
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.
