Dear Team,
I am designing a wearable device which contain a 16 bit ADC (AD5941) . Initially I thought of using LDO ADM7155 . My battery is 3.7V so when I use this LDO there is a tight head room related to dropout voltage.
This make made me to use other options ,I decided to go with a buck boost converter .The selected P/N is ADP2504.
May I know using ADP2504 is a good option or not for powering AD5941.
When powering AVDD and DVDD of the ADC ,I believe I can directly connect the output of AD5941 to DVDD and from DVVD I will generate the AVDD by putting a ferrite bead at the output of DVDD rail.

May I know is this a good option .
You have any suggestion for other methods or part numbers other than AD5941.
Below is the high level architecture of my system.

Regards
HARI
