Description

LM-386 is an audio integrated power amplifier, which has the advantages of low power consumption, adjustable inner chain gain, large power supply voltage range, fewer external components, and low total harmonic distortion. It is mainly used in low voltage consumer products. To minimize peripheral components, the voltage gain is built in at 20. By adding an external resistor and capacitor between pin 1 and pin 8, the voltage gain can be adjusted to any value up to 200.
