LM386N
Low Voltage Audio Power Amplifier
Internal Reference:
LM386
General 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. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation.
Features:
- Battery operation
- Minimum external parts
- Wide supply voltage range: 4V–12V or 5V–18V
- Low quiescent current drain: 4mA
- Voltage gains from 20 to 200
- Ground-referenced input
- Self-centering output quiescent voltage
- Low distortion: 0.2% (AV=20, VS=6V, RL=8W, PO=125mW, f=1kHz)
- Available in 8 pin MSOP package
Applications:
- AM-FM radio amplifiers
- Portable tape player amplifiers
- Intercoms
- TV sound systems
- Line drivers
- Ultrasonic drivers
- Small servo drivers
- Power converters
