Advanced Product Information
PAM8402
2 Watt Class-D Audio
Amplifiers with Enable
Description
The PAM8402 is 2 Watt per channel, 14-
pin, stereo class D audio amplifier,
whitch offers low THD+N (0.10%),
allowing it to produce high-quality sound
reproduction.
The PAM8402 runs off of a 5 Volt supply
at much higher efficiencies than their
class AB cousins, making it ideal for
many portable applications.
The PAM8402 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 SOP14
package.
Features
• 2 Watts @ 10% THD per channel
output into a 8Ω load at 5V
• Support speakers or earphone
(6Ω tο 32Ω).
• Superior low noise without input.
• Supply voltage: From 2.5V to 6 V.
• 85% efficiency above.
• With Enable Function.
• Short Circuit Protection.
• Small package outlines: SOP14
• Less output capacitor and
inductor to save the space and
cost.
• Low THD+N
• Low Quiescent current
Applications
• Notebook computers.
• PDAs.
• Portable DVD players, game machines.
• Cellular phones/speaker phones.
• MP3 or PMP players.
• Portable speakers, USB speaker.
• LCD monitor / TVs.
