ADAU1452 RMS envelope with 100dB dynamic

Hello,

I am using an ADAU1452 for a project and I need to perform an RMS envelope detection with a dynamic range of 100dB. I tried using the RMEnv algorithm with a square root behind. It works well but the dynamic is limited to 72dB, below -72dB the output drops to zero.

Is it possible to perform an RMS envelope detection with 100dB of dynamic range?

Thank you for your reply.
