Class AB Stereo Amplifier (SMD)
This project is a fork of classabstereoamp_smd project created by Hussam Al-Hertani.
A Class AB audio amplifier is a type of hybrid linear amplifier that combines characteristics of Class A (low distortion, high efficiency at low power) and Class B (higher efficiency at higher power) to achieve a balance between efficiency and distortion performance. Unlike pure Class A (100% conduction) or Class B (50% conduction), Class AB amplifiers operate with both transistors conducting partially during signal cycles, reducing crossover distortion while improving efficiency compared to Class A
Class AB amplifiers are the most widely used in audio applications due to their optimal balance between efficiency, distortion performance, and reliability. While not as efficient as Class D amplifiers, they offer superior sound quality for their power level, making them ideal for Hi-Fi systems.
