6W 2-Channel Amplifier Circuit
Working Explanation
IC 4440 amplifier circuits use very few external components. 12V supply input is given to the IC. Audio input is given at pin two of an IC. Pins 9, 10, 12, and 13 are there to drive the load. Hence, in this case, the load is the speaker. Hence, this is how the circuit works.
Application
- For audio amplification.
- Also, the circuit can be utilized in public addressing electronic systems.
- Moreover, in concerts, restaurants, weddings, etc.
