  • Hi, Michele

             TPA3125D2 is 10w/ch (SE) into an 8ohm load from 24V supply and 20w (BTL) into and 8ohm load from a 24V supply.

             The output power mentioned in above sentence are rms power.

             The over current protection trigger point is about 5.7A

    Thanks for your quick reply, but my question is about power supply. I know that is 24V but how many Amperes? I need this info cause I need a power supply for both TPA and preamp.

  • In reply to michele fregoni:

    It depends on your application case? How much power are you need? What is you load impedance?

    8ohm btl. Simple 2 stage fet preamp @ 15V for guitar use. Now I use a 24V 3A switching power supply and it's OK, but if I want to insert a reverb I need 100ma to proper operation of reverb. So I don't know if my 3A power supply (less 100ma of reverb and less 20 - 30 ma of FET preamp) are ok for TPA to operate.
