TAS5631 PWM input - output Delay

Other Parts Discussed in Thread: TAS5631, TAS5261

Hello TI Community.

I have a question about the TAS5631 digital audio amplifiers:


Is there any delay between the lower level PWM input signal and the higher level PWM output signal ?

On the way from the PWM input to output is some logic in the functional block diagram but there are no details.

 

Thanks and Greetings from German

    Hello Mr. Krug

    Yes there is a delay - first the loop filter, then the comparator, then the deadtime control and gatedrive - all in all aprox 300-400nS.

    This is all due to the feedback loop - if you look at our open loop power stages like TAS5261 where there there is no feedback the delay is lower around 150-200nS

     

    Best regards
