EDSADC External C_TANK Capacitor

[shaun_pye]

Hello, 

How can the effectiveness of the external capacitor be evaluated for EDSADC? There is no information about the internal switched capacitor or other circuit elements, or sampling times from what I can see. Only the RMS current draw and equivalent resistance. 

Thank you, 
Shaun
