CLASS D AMPLIFIER BLOCK DIAGRAM
Class-D amplifier - Wikipedia
Block diagram of a basic switching or PWM (class-D) amplifier. Note: For clarity, signal periods are not shown to scale. 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
Class D Audio Amplifiers: What, Why, and How | Analog Devices
Class D open-loop-amplifier block diagram. Since most audio signals are not pulse trains, a modulator must be included to convert the audio input into pulses. The frequency content of the pulses includes both the desired audio signal and significant high-frequency energy related to the modulation process.
Power amplifier classes - Wikipedia
Power amplifier classes. Power amplifier circuits (output stages) are classified as A, B, AB and C for linear designs—and class D and E for switching designs. The classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current. The image of the conduction angle derives from amplifying a sinusoidal signal.
How to Build a Class-D Power Amp - Projects
Aug 29, 2018Because of this, the amplifier does not generate a lot of heat and does not require a big heat sink like linear class AB amplifiers do. For comparison, the class B amplifier can only achieve a maximum efficiency of 78.5% (in theory). Below you can see the block diagram of a basic PWM Class-D amplifier, just like the one that we are building.
MAX98357A Tiny, Low-Cost, PCM Class D Amplifier with Class
The MAX98357A/MAX98357B is an easy-to-use, low-cost, digital pulse-code modulation (PCM) input Class D amplifier that provides industry-leading Class AB audio performance with Class D efficiency. The digital audio interface automatically recognizes up to 35 different PCM and TDM clocking schemes which eliminates the need for I 2 C programming.

What are the Different Types of Audio Amplifier Classes
Of course, as amplifier manufacturers try to push the envelope of power delivery with amplifiers like the 1,000 watt Emotiva XPR-1 Mono-Block, they turn to Class G/H and Class D designs to avoid having their amplifiers double as space heaters. Meanwhile, on the other end of the market are Class A aficionados who can forgive a lack of efficiency[PDF]
