1Gain is measured as a ratio of the full-scale current to ISet. The ratio is nominally 128.
2Measured as voltage at mid-scale transition to ±0.024%; RL=50 Ω.
3Measured from the rising edge of Latch Enable to where the output signal has left a 1 LSB error band.
4Glitch is measured as the largest single transient.
5Calculated using IFS = 128 x (Control Amp In / RSet)
6SFDR 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.
