PAM8202
Tiny Package 2 Watt Class-D Stereo Audio Amplifier
DESCRIPTION
The PAM8202 is a 2 Watt per channel, 8-pin, stereo
class D audio amplifier, which offers low THD+N
(0.10%), allowing it to produce high-quality sound
reproduction.
The PAM8202 runs off of a 5 Volt supply at much
higher efficiencies than their class AB cousins,
making it ideal for many portable applications.
The PAM8202 only requires very few external
components (as few as three tiny capacitors),
results in significant cost and board space savings.
The PAM8202 is available in a SOP8 package.
TYPICAL APPLICATION CIRCUIT
FEATURES
