ADC NOISE PERFORMANCE TABLES
Table 32, Table 33, and Table 34 show the output rms noise in microvolts (μV) for some typical output update rates on the I-, V-, and
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 one sigma) of the distribution of ADC output codes collected when the ADC input voltage is at a dc voltage. It is expressed
as microvolts rms (μV rms).
