LM386 Datasheet (Texas Instruments) - Low Voltage Audio Power Amplifier

LM386, Low Voltage Audio Power Amplifier

The LM386M-1 and LM386MX-1 are power amplifiers 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 increases the gain to any value from 20 to 200.
