LM386 - Low Voltage Audio Power Amplifier

Description

The LM386M-1 and LM386MX-1 are power amplifiers 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 pins 1 and 8 increases the gain to any value from 20 to 200.

Features

  • Battery Operation.
  • Minimum External Parts.
  • Wide Supply Voltage Range: 4 V.
  • 12 V or 5 V.
  • 18 V.
  • Low Quiescent Current Drain: 4 mA.
  • Voltage Gains from 20 to 200.
  • Ground-Referenced Input.
  • Self-Centering Output Quiescent Voltage.
  • Low Distortion: 0.2% (AV = 20, VS = 6 V, RL = 8 Ω, PO = 125 mW, f = 1 kHz).
  • Available in 8-Pin MSOP Package 2.
