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.

IC LM386 LM386 IC is a power amplifier used to amplify the small audio signals with the supply of low voltages. Even though internally the gain of IC LM386 is set at 20 but, by adding a resistor and a capacitor at pins 1 and 8 of the IC, we can raise this gain up to 10 times higher than internal gain i.e., up to 200. IC LM386
