PAM8101/8201
Tiny 1.2 Watt Class-D Audio
Amplifiers
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 8Ω speaker at
much higher efficiencies than their
class A/B cousins. They also offer
low THD+N (0.10%), allowing them
to produce high-quality sound
reproduction.
The PAM8101 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.
The PAM8101 and PAM8201 both
run off of a 5 Volt supply, making
them ideal for many portable
applications.
Features
• 1.2 Watts @ 10% THD per channel
output into a 8Ω load at 5V
• Support speakers or earphone
(6Ω tο 32Ω).
• Superior low noise without signal
input.
• Supply voltage: From 2.5V to 6 V.
• 85% efficiency above.
• Short Circuit Protection.
• Tiny package outlines: SOT25
(PAM8101) and SOP-8 (PAM8201)
• Less output capacitor and inductor
to save the space and cost.
• Low THD+N
• Low Quiescent current: Below 10mA
Applications
• Notebook computers
• PDAs
• Portable DVD players
• Cellular phones/speaker phones.
• MP3 or PMP players.
• Portable speakers.
• USB speaker.
• LCD monitor / TV.
