Comparison Table: Class AB vs. Class D

Criteria Class AB Class D
Operating Principle Operates on both transistors (NPN and PNP) in active regions. Uses PWM (Pulse Width Modulation) to convert analog signals into digital signals.
Energy Efficiency Around 50-70%. A significant portion of energy is lost as heat. Very high efficiency, up to 90-95%, as transistors operate as switches.
Sound Quality Warm, full sound, less distortion, particularly suited for music and vocals. Slightly inferior to Class AB at high frequencies, but has improved significantly.
Total Harmonic Distortion (THD) Low distortion at medium power, but may increase at high power levels. Higher distortion at medium and high frequencies if not optimized.
Heat Dissipation Generates more heat, requiring large heat sinks. Minimal heat generation, no need for large heat sinks.
Size and Weight Larger in size and requires a heat dissipation system. Compact and lightweight, ideal for portable designs.
Main Applications Used in high-end devices like hi-fi amplifiers or premium karaoke systems. Common in portable speakers, subwoofers, and devices requiring high efficiency.
Cost Typically higher due to more complex circuitry. Lower due to simpler and more compact design.
Noise Level Low noise, suitable for accurate sound reproduction. Potential noise due to switching, but mitigated through filtering.
Durability Relatively durable, but heat dissipation may affect lifespan. High durability with stable operation in different conditions.
