1 The supply current values for both 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 6 through Figure 8 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 9 through Figure 11

for total IDD1 and IDD2 supply currents as a function of data rate for ADuM1200 and ADuM1201 channel configurations.

2 The minimum pulse width is the shortest pulse width at which the specified pulse-width distortion is guaranteed.

3 The maximum data rate is the fastest data rate at which the specified pulse-width distortion is guaranteed.

4 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.

5 tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH that is measured between units at the same operating temperature, supply voltages, and output

load within the recommended operating conditions.

6 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.

7 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.

8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate. See Figure 6 through Figure 8 for

information on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating per-channel supply

current for a given data rate.
