Insider High Power Class D Amplifier Schematic
Circuit diagram. Class D amplifier circuit BD5460 Notes. The power supply voltage can be between 2.5 to 6.5V DC. For the circuit shown here, the supply voltage must be 3.6 V DC. Powering the circuit from a battery is the better option because it reduces noise. If you are using a DC power supply, then it must be well regulated and filtered.
Class D Amplifier Circuit Diagram
What is a Class-D audio amplifier? The simplest answer will be, it's a switching amplifier. But in order to understand its working, we need to learn how it functions and how the switching signal is produced, for that, you can follow the block diagram given below. So why a switching amplifier? The obvious answer to this question is Efficiency.
