The PAM8403 5V Two-channel Stereo is a 3W+3W, class-D audio amplifier. Allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area. With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications.
Features :
- Dual channel stereo, high output power (3 w + 3 w power @ 5V and 4 ohms load).
- Good sound quality.
- Double panel wiring solves crosstalk.
- Super mini design allows it to be easily placed in a variety of digital products.
- 3W Output at 10% THD with a 4ΩLoad and 5V Power Supply.
- Filterless, Low Quiescent Current and Low EMI.
- Superior Low Noise.
- Short Circuit Protection.
- Thermal Shutdown
Application :
- Bluetooth Stereo Audio hands-free/headsets
- In robots that speak or generate sounds to indicate activities
- Portable Speakers
- LCD Monitors / TV Projectors
- Arduino or Raspberry Pi Game Machines
- Speaker Phones
Package Includes :
1 x PAM8403 5V Two-channel Stereo Mini Class-D Audio Amplifier.

sound quality is average at 70% volume and worst at 100% volume. i dont think it is class d amplifier.
could be use in project. but don’t expect that you can use it as speaker for smartphones or computer because it isn’t louder than a smartphone.

Although it works just fine, it’s not orignal PAM 8403 module. It’s a copy based on PAM 8403 chip. There’s not much difference but I have noticed a slight difference in durability between orignal and copies. Rest it works when used the it’s suppose to be used.

Pretty good amplifier for such a low price..good sound quality if paired with good quality speakers..one tip you can use a 5w speaker with it if you just use one channel and connect the right and left channel to just one channel on the amplifier..it works pretty well

First of all thank you Robu, this is my first purchase from this website, on 29th may and product is delivered within 5 days or less. Then after one week leaving this alone, On Thursday i started working on this module, I done the all the necessary things which the module is required that one lead cable which connects to smartphone and one is data cable which provide 5V to this board and also connected two speakers with it. After finishing all the things then it’s testing time ? then I plug the data cable in adaptor and adaptor in electric socket, and connect the lead to the smartphone and switch on the power supply and play the song, the output of sound quality is awesome and i impressed with this module.
last thing which is at 90% or 100% bass or sound quality is not good means not very clear but all other things are very good.
Again ? Thanks Robu only one suggestion please remove shipping charges. Hope helpful for u.
