Description

PAM8406 Class -D Audio Amplifier Module With Volume Control Potentiometer is an excellent noise suppression module. If you don’t receive input audio, you will not hear any noise in your ears.

PAM 8406 is a Class-D audio amplifier that can be powered using simple 3V-5V input and produces an output of 10W (5W+5W). It can receive the audio in any form like MP3, MP4, etc. It’s very easy to connect and operate. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters. With the same numbers of external components, the efficiency of the PAM8406 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications.
This Amplifier allows the user to achieve high-quality audio reproduction from a stereo input. Additionally, it has a special feature that is, it can drive speakers directly from its output. It is a 3watt Class-D stereo amplifier capable of operating on a voltage as low as 2.5 V and up to a maximum of 5 V. The total harmonic distortion plus noise is as little as 0.11 %, which allows this chip to produce a very high-quality sound reproduction. With good speakers, you should get the entire bass and tone that you would not normally be able to hear in a conventional Class AB. This chip provides a pulse width modulated output to drive a conventional loudspeaker. It has a dedicated pair of pins for each channel output. There is no common ground (this means the negative output of the left speaker and the negative output of the right speaker are not the same you cannot connect them together).

 

Features

  • To enhance the sound quality PAM 8406 is a better option.
  • Mini design allows it to be easily placed in a variety of digital products.
  • PAM 8406 works with 3v-5v.
  • Superior Low Noise
  • Efficiency up to 90%
  • Short Circuit Protection
  • Thermal Shutdown
  • It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filter-less 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.
  • The IC does not require a heat sink, so this will be perfect for your custom speaker project.
  • Volume Control Potentiometer is an excellent noise suppression module
