Pin2 (+IN-Non-inverting): Pin-2 is the non-inverting pin, is used to provide the audio signal.Pin1 (Ga+-gain Pin): Pin-1 is gain pin, used adjust the amplifier gain by connecting this IC to an external component capacitor.The IC LM386 audio amplifier consists of 8-pins where each pin of this IC is discussed below. This amplifier consists of 8-pins where pin-1 and pin-8 are gain control pins of the amplifier, and this IC is most widely used IC that allows a customer to increase volume. When this amplifier uses a 6V power supply for the operation then the static power drain will be 24 milliwatts to make the amplifier for an ultimate operation of the battery. The voltage gain of this amplifier can be adjusted to 20, and the voltage gain will be enhanced to 200 by employing external components like resistors as well as capacitors among the pins 1 & 8. This IC is available in the package of mini 8-pin DIP. The IC LM386 is a low-power audio amplifier, and it utilizes low power supply like batteries in electrical and electronic circuits. Voltage gain of this amplifier can be adjusted to 20, and gain voltage will be 200 by connecting external components like capacitors as well as resistors among the pins no 8 and 1. IC LM386 is a famous low power audio amplifier,it consume low power supply like batteries in electronics and electrical circuits. The IC LM386 available in different 8 pin package. Following circuit can be used for minimized public addressing Audio amplifier.
