Hi
In the ADC10D1000 datasheet (page 19) the Vcmo Lim tolerances are stated as 1.15V and 1.35V, Vcmo nominal 1.25V. Temperature coefficient of 38ppm/C is also given
Why are the Lim tolerances so big (1.15V to 1.35V) when Vcmo "is generated as a buffered verison of the internal bandgap reference" (page 53) ?
Does Vcmo actually reflect the bandgap reference voltage or is Vcmo adjusted during calibration or otherwise?
Thanks
Johan
