Key Features
General Description
The PAM8101 is a 1.2 Watt, 5-pin, single channel,
class D audio amplifier. The PAM8201 is a 1.2
Watt per channel, 8-pin, dual channel, class D
audio amplifier. The PAM8101 and PAM8201
require very few external components, which
leads to lower total system costs as well as less
board space.

These amplifiers supply 1.2 Watts per channel
into a 8 speaker at much higher efficiencies than
their class A/B cousins. They also offer low
THD+N (0.10%), allowing them to produce highquality sound reproduction.
The PAM8 101 is available in a SOT25 package,
which is a tiny 2mm by 3mm. This small package,
combined with the low external component count
(as few as two tiny capacitors), results in
significant board space savings.

The PAM8201 is available in a small 8-pin SOP
package, and requires as few as three tiny
capacitors for a complete class-D solution. As
with the PAM8101, this small package, combined
with the low external component count, results in
significant board space savings.
