Part Number: TAS5634
Other Parts Discussed in Thread: TAS5631,

Hi Team,

For 200WX2/4Ohm  , TAS5634 can work continuous 180 seconds on BTL mode,  How about TAS5631? which solution would working longer( same heatsink size and same power supply)  ? any difference on THD ?

Thanks and regards

    Hi Eric

         TAS5631's efficiency is a little better than TAS5634, so with the same working conditions, TAS5631 should be better.

         The only way they can use is to reduce the PWM frequency, no doubt it would affect the THD, they need to test to find a balanced position.
