4.5 V ≤ VDD1 ≤ 5.5 V , 4.5 V ≤ VDD2 ≤ 5.5 V; all minimum/maximum specifications apply over the entire recommended operation range, unless otherwise noted; all typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V . These specifications do not apply to ADuM1400W , ADuM1401W, and ADuM1402W automotive grade versions.

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 section. See F through F for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See F through for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1400/ADuM1401/ADuM1402 channel configurations. Power Consumption igure 8 igure 10 igure 11 Figure 15

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.

Power Consumption Figure 8 Figure 10 9 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See through for information on per-channel supply current for unloaded and loaded conditions. See the section for guidance on calculating the per-channel supply current for a given data rate.
