LM386 Low Voltage Audio Power Amplifier COM21

Description

The LM386 is a power 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.

• The inputs are ground referenced while the output automatically biases to one-half the supply voltage.
• Battery operation
• Minimum external parts
• Wide supply voltage range: 4V–12V or 5V–18V
• Low quiescent current drain: 4mA
• Applications:

1. AM-FM radio amplifiers
2. Portable tape player amplifiers
3. Intercoms
4. TV sound systems
5. Line drivers
6. Ultrasonic drivers
