Audio Amplifier Using LM386
Description: The LM386 is an audio amplifier 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.
You can use this useful audio amplifier for following applications:
- AM-FM radio amplifiers
- Portable tape player amplifiers
- Intercoms
- TV sound systems
- Line drivers
- Ultrasonic drivers
- Small servo drivers
- Power converters
This audio amplifier module can be used to play your FM receiver kit, make infrared based music transmitter and receiver, etc.
