UTC 3544

      The UTC 3544 is digital-source dual headphone amplifier.The UTC 3544 has a fixed gain of 6dB so that external gain setting is unnecessary. The UTC 3544 has internal mute function to prevent popping sounds when the power is turned on and off.Also, The UTC 3544 is equipped with thermal shutdown circuits to prevent damage to the IC if a short circuit occurs.It is widely use in the devices that use the headphone output from CD-ROMs,CDs, MDs, personal computers, notebook computers,camcorders, etc.
      Then we give you some information about the absolute maximum ratings.The first one is that the applied voltage (V_max) is 7V.The second one is that the power dissipation (P_D) is 450mW.The third one is that the operating (T_opr) temperature ranges from-25 to +75.The fourth one is that the storage temperature (T_stg) ranges from -55 to +125.
      The following is about the recommemded operating condition (Ta=25).The maximum power supply voltage of the UTC 3544 (V_cc) is 6.5V and the minimum is 2.8V.
