LM386 - LOW VOLTAGE AUDIO POWER AMPLIFIER

Download the LM386 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same low voltage audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The UTC 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 pin 1 and pin 8 will increase the gain to any value up from 20 to 200.

UNISONIC TECHNOLOGIES CO., LTD LM386 LINEAR INTEGRATED CIRCUIT LOW VOLTAGE AUDIO POWER AMPLIFIER  DESCRIPTION The UTC 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 pin 1 and pin 8 will increase the gain to any value up from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation.
