LINEAR INTEGRATED CIRCUIT
HEADPHONE AMPLIFIER FOR
CD-ROMS
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. To prevent damage from short circuits
the UTC 3544 is equipped with thermal shutdown circuit.
FEATURES
* 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.
