PAM8403 Digital Power Amplifier Module is a 3W, class-D stereo amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction, all in a form factor about the size of a US postage stamp.
It can be used in any DIY design requiring a miniature amplifier, especially portable and mobile applications operating on battery power.
Features:
1. Working voltage: 2.5V-5.5V. Note: the power supply voltage should not exceed 5.5V, and the positive and negative power supply
should not be connected inversely.
2. Speakers with: 4-8 euros, recommended: 4 euros; Horn power: 2-8W.
3. It can be powered by COMPUTER USB port 5V power supply, mobile phone charger USB port 5V power supply or lithium battery power supply.
4. High efficiency 90%, 4 ω load and 5V power supply conditions, can provide 3W (left channel) +3W (right channel) output power. Theefficiency of class A and B power amplifiers is only about 30%, and class D power amplifiers are highly respected under the current green trend.
5. Class D power amplifier efficiency is extremely high, will not affect the sound quality because of the temperature rise, and do
not add heat sink, occupy a small volume.
Application:
LCD TV, monitor
Laptop computer
Portable loudspeaker
Portable DVD player, game console
Cell phone/speakerphone
Precautions for use:
Connect the speaker first and then the power supply, otherwise it is easy to damage the chip; Because the digital volume control in the module has a large gain, do not let the audio signal input too large to cause the signal cutting limiter.
