Relative accuracy is the deviation of the analog value at any code from its theoretical value after full-scale range has been
calibrated.
Offset and reference errors nulled.
DC voltage applied to on channel, and a full-scale 1kHz sine wave applied to off channels.
Conversion time is measured from the rising edge of the 8th external SCLK pulse to EOC transition minus t
data-transfer mode.
See Figures 10 and 17.
