Note that minimum gain for LM386 is \$ v_{out} / v_{in} = 20 \$. You can raise the gain by making R3 a variable resistor. It is paralleled with an internal resistance of 1350 ohms. If R3 is infinite, gain is 20. In this condition, you have maximum feedback, lowest distortion.

The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.

A close look at the LM386’s internal schematic shown in Figure 1 reveals that its voltage gain is determined by the ratio of its internal feedback resistors and the value of an optional (external) bypass resistor. If no bypass resistor is added, the device’s single input voltage gain is equal to 15,000/ (1350+150)=10.

The LM386 is a low power audio frequency amplifier which is very commonly used in small audio amplifiers. The IC consumes very less power and hence can be operated using a 9V battery easily. It can easily drive an 8-ohm speaker with a variable gain of 20 to200. Volume control and gain control is also possible in this.
