LM386 Audio Amplifier Module

LM386 Audio Amplifier Module 200 Times Input 10K Adjustable Resistance designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24 mW when operating from a 6-V supply, making the LM386 ideal for battery operation.

If your project needs an audio amplifier, this module should be useful. It is a miniature module for amateur projects. Simply connect a 4-8 Ohm speaker and amplify your sound. It can be used with the FM receiver kit or WTV020SD-16P music module. You can definitely use this module for other musical projects also. The chip pin leads can directly input audio signal.
