Note: INL and DNL are referenced to a LSB of the Equivalent ADC Bits shown in the last row of Table 10-6.
ENOB (effective number of bits) can be calculated from either SNR (signal to non-harmonic noise ratio) or
SINAD (signal-to-noise and distortion ratio).
Table 10-7 describes the key ADC parameters measured at 25°C and VDD_PADS at 3.0 V, for a sampling rate of
6 MHz. The single-ended measurements were done at f
V p-p swing). The differential measurements were done at f
a 2.4 V p-p swing) and a common mode voltage of 0.6 V.
