1 _{All voltages are relative to their respective ground.}
2 _{The supply current values for all four channels are combined when running at identical data rates. Output supply current values are specified with no output load}
present. The supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section.
See Figure 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through
Figure 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1400W/ADuM1401W/ADuM1402W channel configurations.
3 _{The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.}
4 _{The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.}
5 _{tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is}
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
6 _{tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load}
within the recommended operating conditions.
7 _{Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of}
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier.
8 _{CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate}
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.
9 _{Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information}
on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current
for a given data rate.
