Amplifier using LM386

IC LM386 Is A well-known Low energy Audio Amplifier, It eats Low power deliver Like Batteries In Electronics And electrical Circuits. This IC includes eight Pins. The voltage gain Of This Amplifier can be Adjusted to 20, And the benefit Voltage might be two hundred by Connecting outside components Like Capacitors as well as Resistors among the Pins No eight And 1. As the Amplifier uses 6 Volts power deliver For Operation Then The Static power Drains 24 Mill Watts To Make The Amplifier. This IC includes 8-Pins in which Pin-1 And Pin-8 Are the advantage manipulate Of The Amplifier.
