ADC NOISE PERFORMANCE TABLES
Table 25, Table 26 and Table 27 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.
