Hi Team,

May I know what is the ENOB will be(how many bits) while set the PGA is 128?

I cannot find it in the datasheet.

Hi Peter,

equation (2) in the datasheet shows how to calculate effective resolution in bits from the rms noise numbers provided in table 7-1.
In addition, Table 7-2 shows the calculated effective resolution numbers in parenthesis.
