LM386 Low Voltage Audio Power Amplifier IC DIP-8 Package
The LM386 is 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.

Description
The LM386 is 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 mW when operating from a 6-V supply, making the LM386 ideal for battery operation.
Features:-
- Battery Operation
- Minimum External Parts
- Wide Supply Voltage Range: 4 V?12 V or 5 V?18 V
- Low Quiescent Current Drain: 4 mA
- Voltage Gains from 20 to 200
- Ground-Referenced Input
- Self-Centering Output Quiescent Voltage
- Low Distortion: 0.2% (AV = 20, VS = 6 V, RL = 8 ?, PO = 125 mW, f = 1 kHz)
- Available in 8-Pin MSOP Package
