LM386A - LOW VOLTAGE AUDIO POWER AMPLIFIER

Download the LM386A datasheet PDF. This datasheet also covers the LM386 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.

Description

The 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.

Features

  • Battery Operation.
  • Minimum External Parts.
  • Wide Supply Voltage Range: 4V~12V.
  • Low Quiescent Current Drain:4mA.
  • Voltage Gains:20~200.
  • Ground Referenced Input.
  • Self-Centering Output Quiescent Voltage.
  • Low Distortion:0.2%(Av =20,Vs=6V,RL=8Ω,Po=125mW,f=1kHz).

LM386(A) LOW VOLTAGE AUDIO POWER AMPLIFIER DESCRIPTION The 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 voltage supply, making the LM386 ideal for battery operation.
