1 VDE = differential error voltage, VCME = common-mode error voltage, ΔVDE = VDE matching between outputs, ΔV = maximum deviation between outputs, and full-scale output
voltage = VFS = 2 × (VRH − VRL). See the Accuracy section.
2 Guaranteed monotonic by characterization to four sigma limits.
3 Measured on two outputs differentially as CLK and DBx(0:11) are driven and XFR is held LOW.
4 Measured on two outputs differentially as the others are transitioning by 5 V. Measured for both states of INV.
5 Measured from 50% of rising CLK edge to 50% of output change. Measurement is made for both states of INV.
6 Measured from 50% of INV transition to 50% of output change.
7 Operation at elevated ambient temperature requires a thermally optimized PCB and additional thermal management, such as airflow across the surface of the AD8387.
