UTC 3541

      The UTC 3541 is a class AB stereo headphone driver with mute feature.Here you can get some informatio about the features. There are six features as follows.The first one is that it has a built-in mute function.The second one is that it has no switch ON/OFF pops.The third one is that it has short-circuit protection.The fourth one is that the power consumption is low.The fifth one is that the output voltage swing is large.The last one is that it has high Signal-to-Noise ratio.
      Then we give you some information about the absolute maximum ratings of the UTC 3541. The first one is that the supply voltage (V_DD) is 7V.The second one is that  the electrostatic discharge (V_ESD) ranges from -3000 to 3000V.The third one is that the output short-circuit duration (Ta=25, P_tot=1W) (t_sc(o)) is 20S.The fourth one is that the operating ambient (T_a) temperature ranges from -40 ~ 85.The fifth one is that the maximum junction temperature (T_j) is 150.The sixth one is that the storage temperature (T_stg) ranges from -65 ~ 150.The last one is that the soldering temperature (T_solder)(10 seconds)  is 260.
      The UTC 3541 has two types which are DIP-8 and SOP-8.Then we introduce their thermal characteristics. The _JA(Thermal Resistance from Junction to Ambient in Free Air) of DIP-8 is 109K/W and the _JC(Thermal Resistance from Junction to Case) is 45K/W. The _JA of SOP-8 is 210K/W and the _JC is 40K/W.
