Tiny Package 2 Watt Class-D Audio Amplifiers With Enable
The PAM8302 is a 2 Watt, 8-pin, class D audio
amplifier with Enable function, it offers low THD+N
(0.10%), allowing it to produce high-quality sound
The PAM8302 runs off of a 5 Volt supply at much
higher efficiencies than their class AB cousins,
making it ideal for many portable applications.
The PAM8302 only requires very few external
components (as few as two tiny capacitors), results
in significant cost and board space savings.
The PAM8302 is available in a SOP8 package.
