Preliminary Technical Data
ADC NOISE PERFORMANCE TABLES
Table 19, Table 20 and Table 21 below show the output RMS noise in μV for some typical output update rates on the I and V/T ADCs.
The numbers are typical and are generated at a differential input voltage of 0 V The output RMS noise is specified as the standard
deviation (or 1 X Sigma) of the distribution of ADC output codes collected when the ADC input voltage is at a dc voltage. It is expressed
as V RMS.
