What is ADXL362 converting time when using external sync trigger?

I have a battery powered system which has some relatively high current, periodic processes that drop the battery voltage for short periods and I'd like to sync ADXL362 to only sample and convert in periodic time windows when I know those processes are off and the voltage on the bus is stable.


I would like to know how long does the converting process take, after the external sync trigger, in order to avoid compromise the sample with noise in the VDD during the conversion.Is it a function of the configured bandwidth?


I think the SPI reading itself is less sensitive to noise and I could read it even during the voltage drops, but if noise gets into the converting process the whole system performance is being affected.


Thank you in advance.
