SMSL A1 High Resolution Power Amplifier AMP Small Delicate Class A Amplifier Volume control chip PGA2311
Design Of Optimal Sound Amplifier Circuit
The working mode of the Class A power amplifier has the best linearity.
Each output transistor amplifier the full wave of the signal, and there is no Switching distortion. Even if it is not negative feedback, its open loop distortion is still very low.
Transparent sound Rich in details
Class A power amplifier is an ideal choice for spreading music. It can provide a very smooth sound quality, a round and warm tone, and a cold and ethereal treble. Class A power amplifier has the advantage of fullness and transparency,and it is to bias the square at half of the maximum output power, so that the power amplifier is in full load working state when there is no signal input, so that the power amplifier is turned on and has current output during the entire signal cycle. The Class A power amplifier makes the transistor always work in the linear region, so the Class A power amplifier has almost no distortion, and the quality of the hearing is particularly good, especially when the signal issmall, the whole sound is transparent and rich in details.
