Low Power Audio Amplifier using 555 Timer
https://circuit-diagramz.com/low-power-audio-amplifier-using-555-timer/
Circuit Design of Low Power Audio Amplifier: The circuit design method is straightforward, with only two steps: creating the preamplifier portion and designing the astable multivibrator section. We’re using the TL071 low noise JFET input operational amplifier, which has a low input bias current and a fast slew rate of roughly 13V/s.

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.

It is given as. gm = Delta (ID) / delta (VGS) (2) To produce the desired gain three potential divider biased circuits were cascaded in series and the total gain is the product of the gains of individual stages. Total Gain = A1*A2*A3 (3) Where, A1, A2 and A3 are the gains of first, second and third stage respectively.
