A Switching Amplifier, also known as a Class D amplifier, represents a specific operating mode of amplifiers. They are widely used in applications like AC power supplies, general-purpose inverters, speakers for portable electronic devices, and slim televisions.
Notable for their compatibility with various power sources, including car batteries and Switched-Mode Power Supplies (SMPS), these amplifiers are also known for generating minimal heat. This, combined with their compact circuit size, leads to high power efficiency and cost-effective operation.
These amplifiers work by modulating the input signal and amplifying it through the switching of the power switch. While efficient, it is important to note that Switching Amplifiers can be sensitive to noise interference, especially in environments with high electromagnetic interference. Despite this, their energy efficiency and high-quality sound output make them a popular choice in various audio and electronic applications.
