A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices transistors, usually MOSFETs operate as electronic switches, and not as linear gain devices as in other amplifiers, They operate by rapidly switching back and forth between the supply rails, being fed by a modulator using pulse width, pulse density, or related techniques to encode the audio
· Unlike the linear and hybrid topologies of their relatives, class D amplifiers deliver punchy sound and plenty of wattage, without the significant heat dissipation and power draw, Aside from being light on energy use, they’re generally quite easy on the wallet, and tend to be among the most compact …
Class D Audio Amplifiers: What, Why, and How
The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion, Audio frequencies range from about 20 Hz to 20 kHz, so the amplifier must have good frequency response over this range less when driving a band-limited speaker, such as a woofer or a tweeter, Power capabilities vary widely depending …
