3544 - HEADPHONE AMPLIFIER

Datasheet Summary

Description

As a dual headphone amplifier the UTC 3544 is digital-source.

The UTC 3544 has a steady gain of 6dB and so it is unnecessary for external gain setting.

The UTC 3544 has internal mute function so that it is greatly simplified for prevention of the popping sound when power is turned on and off.

Features

  • S.
  • Internal mute function to prevent popping sounds when.
  • the power is turned on and off.
  • Built-in thermal shutdown circuit (150°C) to prevent.
  • damage to the IC if a short circuit occurs.
