Class AB

Class AB amplifiers are a type of electronic amplifier that are known for their high efficiency and low distortion. They are called “class AB” because they operate in the “class AB” region of the amplifier’s input/output signal transfer characteristic, which means that the output devices are not conducting current all the time, but are only conducting when it is necessary to amplify the signal.

The following is a list of categories of class AB amplifiers:

  1. High Efficiency: Class AB amplifiers have high efficiency compared to class A amplifiers, which means that they consume less power and produce less heat.
  2. Low distortion: Class AB amplifiers have low distortion, which means that the output signal is a faithful reproduction of the input signal with minimal added distortion.
  3. Power Output: Class AB amplifiers are typically higher power, they are suitable for high-power applications.
  4. Design: Class AB amplifiers are available in various designs such as single-ended, push-pull and hybrid designs.
  5. Sound Quality: Class AB amplifiers are generally considered to have a slightly less warm and natural sound compared to class A amplifiers but they are still considered to deliver good sound quality.
  6. Widely used: Class AB amplifiers are widely used in audio systems, including home theater systems, car audio systems, and professional audio systems.

Overall, Class AB amplifiers are a type of electronic amplifier that are known for their high efficiency and low distortion. They are suitable for high-power applications and are available in various designs. They deliver good sound quality but may have a slightly less warm and natural sound compared to class A amplifiers, but they are widely used in audio systems, including home theater systems, car audio systems, and professional audio systems.
