Hi,

what is the maximum sampling frequency that we can use to read the current?

Is it no-filtered or is there same integration on the raw values?

Thanks

Hello Fabrizio,

The maximum sampling rate is 250ms for current, this is the fastest we update the current register. It is a delta sigma ADC so it is average through the whole sample period.
