Gain is measured as a ratio of the full-scale current to I
Measured as voltage at mid-scale transition to ±0.024%; R
Measured from the rising edge of Latch Enable to where the output signal has left a 1 LSB error band.
Glitch is measured as the largest single transient.
Calculated using I
SFDR is defined as the difference in signal energy between the fundamental and worst case spurious frequencies in the output spectrum window,
which is centered at the fundamental frequency and covers the indicated span.
