However, the apparent power would be dissipated in the amplifier itself. high efficiency of class-AB only exists at full-volume This would be true for low as well as high speaker operation, which is hardly the usual case. At typical volume. listening levels the efficiency is much lower. This phenomenon has brought about the concept of 2.1.

Low Voltage Audio Amplifier. Jim Keith. This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to consider and much to learn. To the best of my knowledge the following information is new to the world.

Class-AB amplifiers. • Lowest idle power loss ratio Up to 650 W output power with only 1 W of idle power loss. Peak Power vs. Continuous Power Audio consists of a small number of peaks with low average power that may allow you to eliminate the heatsink and save space. Selecting the correct package and thermal management is easier with the
