... LM386 Low Voltage Audio Power Amplifier General Description The LM386 is a power amplifier designed for use in low volt- age consumer applications. The gain is internally set 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 ...

... Application Hints GAIN CONTROL To make the LM386 a more versatile amplifier, two pins (1 and 8) are provided for gain control. With pins 1 and 8 open the 1.35 k resistor sets the gain at 20 (26 dB capacitor is put from pin bypassing the 1.35 k gain will 200 (46 dB resistor is placed in series with the capacitor, the gain can be set to any value from 20 to 200 ...
