UTCLM386 - LOW VOLTAGE AUDIO POWER AMPLIFIER

General Description

The UTC 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, but the additional of external resistor and capacitor between pin 1 and pin 8 will increase the gain to any value up to 200.

Key Features

  • Minimum external parts.
  • Wide supply voltage range:.
  • Voltage gains:20~200.
  • Ground referenced input.
  • Low distortion 4V~12V DIP-8 PIN.
