Description

PAM8403 Stereo Audio Amplifier

This tiny amplifier operates on 5v dc and produces an output of 6w (2×3 w). This is one of the cheapest and most powerful stereo amplifier, provided with proper wiring and power sources. The ic does not require a heat sink, so this will be perfect for your custom speaker project. This amplifier costs about 80 cents in the u.S and around 50 rupees in India. The dimension of this board is 2cm x 2cm only. Don’t short the grounds of the left and right audio outputs without using a. There will be a schematic below if you want to attain common ground for making headphone amps. Avoid providing more than 6 volts. I will definitely not recommend you to build this on a breadboard, the distortion rates are horrible. Use co-axial cables for the dc input and audio input. Failing to do so will result in horrible rf interference and bad audio output. The amplifier board comes in two versions, one with volume control and one without. There’s a schematic below to add your own volume control.

Feature:

Can use the computer USB port 5V power supply or using a mobile phone charger USB port 5V power supply
Battery power can also be used
High efficiency: 90%
Can provide 3W (left channel) + 3W (right channel) output power in the 4Ω load and 5V power supply conditions
A class, B class amplifier such efficiency is only about 30%
D class amplifier is highly respected today
D class amplifier efficiency is extremely high, not because of temperature affect the sound quality
But do not add heat sink and take less space noise cancelling circuit was built in the amplifier board
Power on / off without pop noise
Module has a short-circuit current protection and over-temperature protection

Application:

LCD TVs, monitors
Laptop
Portable Speakers
Portable DVD players, game consoles
Phone / speakerphone
