Class D

Class D amplifiers are a type of electronic amplifier that are known for their high efficiency and compact size. They are called “class D” because they operate in the “class D” region of the amplifier’s input/output signal transfer characteristic, which means that the output devices are switched on and off very quickly in order to amplify the signal.

The following is a list of categories of Class D amplifiers:

  1. High Efficiency: Class D amplifiers have high efficiency, up to 90%, which means that they consume less power and produce less heat compared to other amplifier classes.
  2. Compact Size: Class D amplifiers are known for their compact size, which makes them suitable for portable and space-constrained applications.
  3. Low distortion: Class D amplifiers have low distortion, which means that the output signal is a faithful reproduction of the input signal with minimal added distortion.
  4. Power Output: Class D amplifiers are typically higher power, they are suitable for high-power applications.
  5. Sound Quality: Class D amplifiers are generally considered to have a slightly less warm and natural sound compared to class A and AB amplifiers but they are still considered to deliver good sound quality.
  6. Widely used: Class D amplifiers are widely used in portable audio systems, car audio systems, and professional audio systems.

Overall, Class D amplifiers are a type of electronic amplifier that are known for their high efficiency and compact size. They are suitable for high-power applications and are widely used in portable audio systems, car audio systems, and professional audio systems. They deliver good sound quality but may have a slightly less warm and natural sound compared to class A and AB amplifiers.
