LM386 Datasheet (HTC) - Low Voltage Audio Power Amplifier

LM386, Low Voltage Audio Power Amplifier

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 up to 200.

The inputs are ground ref
