Cyton Max Voltage Reading
I have been looking at the ads1299 chip datasheet and am unable to find the maximum voltage the chip is trying to read. i found this chart and am a little confused. 
does this mean the highest voltage i can measure is 3.9V +0.3V which is 4.2V?
The reason i ask this is because i dont want to break the ads inside the cyton but also am interested in looking at the resolution i have with the 24 bits of data per channel. 2^24 is 16777216 which when diving that number by 4.2 gives me 0.25033950805*10^-6 V or 0.2503uV right?
Is there something im missing in my calculations or am i just really far off?

Mike, hi.
The actual number is .02 microvolts for the lowest order bit in the 24 bit value. See the section on this page: "Interpreting the EEG Data"
https://docs.openbci.com/docs/02Cyton/CytonDataFormat
Actually sub-microvolt resolution like this is mostly noise. So you can consider the lowest order bits of the 24 bit values as just noise when the Cyton is in the default scale factor.
