The internal circuit diagram of the pam8403 module is shown below. This ic can directly drive output speakers.
Pam8403 Amplifier Circuit Diagram. It uses minimum components and its ideal for beginners and learners. Web ic pam8403 offers low thd+n allowing it to achieve high quality sound reproduction. Web in this video, i will show you how to make an audio amplifier using pam8403 and also how to add a potentiometer to the circuit.
Similarly, pin 10 is the right channel input. Web below is the circuit diagram of pam8403 powerful stereo amplifier. But it is recommended to use 5v input for maximum output performance.
This tiny amplifier operates on 5v dc and produces an output of 6w ( 2 x 3 w ). The first stage's gain is externally configu rabl e, while the second stage's is internally fixed. Web pam8403 amplifier board interfacing diagram.
Web as shown in block diagram (page 2), the pam8403 has t wo internal amplifier stages. Two 22uh inductors are used in series with load resistor to emulate the small speaker for efficiency measurement. The first stage's gain is externally configurable, while the second stage's is internally fixed.
The output of that channel is taken at pin 1 ad 3, pin 1 is the positive output, and pins 3 provides the negative output for the left channel. The internal circuit diagram of the pam8403 module is shown below. This is one of the cheapest and most powerful stereo amplifier, provided with proper wiring and power sources.
