HELP IC RMS TO DC

Hello friends.
I need an IC RMS TO DC CONVERTER with some features that I can not see clearly in the datasheets (AD637, AD536, AD637 for example).
. Input signal:
- Not more than 1 vrms
- Various waveforms
- Up to 1MHZ is more than enough
- Best possible accuracy. Example: 100mvrms = 100mvdc.
I'm counting on your help.

  • Thanks for answering me...
    The ic LTC1968 is good.

    After some research I saw that the AD8436 seems to suit me perfectly.
    I still have some doubts:
    - For safety, would it be necessary to stabilize the signal to be measured before applying VIN?
    For I am dealing with sensitive signals and must be faithful. Example:
    When applying 50mvrms to VIN, it drops to 45mvrms. This can not happen because it would not be true to my monitoring (even if I generate 45mvdc in OUT).
    If this happens I would have to check this signal somehow (I still do not know how).
    - I do not find this IC in Brazil.
    I was still testing and would like to know how to get 1 or 2 samples.
    Thank you.
