WebThe Class-D Ampli fier (From the book Introduction to Electroacoustics and Audio Ampli fier Design, Second Edition - Revised Printing, by W. Marshall Leach, Jr., published by Kendall/Hunt, °c 2001.) A class-D amplifier is one in which the output transistors are operated as switches. When a transistor is off, the current through it is zero. WebGenerally, a Class-D amplifier can be manipulated to provide different levels of power by topology. For example, a Class-D amplifier with four half-bridges can drive 4, 2 or even just 1 channel. These topologies are referred to as single-ended (SE), bridge-tied load (BTL), and parallel bridge-tied load (PBTL). Bridging consumer market examples WebMay 12, 2024 · The obvious answer to this question is Efficiency. Compared to Class A, Class B, and Class AB amplifiers, the Class D audio amplifier can reach an efficiency of up to 90-95%.
