TAS2521: replacement with TAS2505

Hi, team,

My customer designed TAS2505 in their previous project, now they would like to add DRC function, I checked in ESP that TAS2521 is pin to pin with TAS2505.

In block diagram, the only difference is mini DSP in TAS2521.

I need double confirm with below questions.

1. Can we just replace TAS2505 with TAS2521 and do not change any hardware on board for verification?

2. Is the register map and setting of TAS2521 exactly the same with TAS2505 except mini DSP?

Thanks.

Johnny
