LM386
DESCRIPTION
The LM386 is a power amplifier, designed for use in low voltage consumer applications. The gain is internally set to 20 keep the external part count low,
SOP-8 but the additional of external resistor and capacitor between pin 1 and pin 8 will increase the gain to any value up to 200.
FEATURES
