All voltages are relative to the respective ground; 4.5 V ≤ V DD1 ≤ 5.5 V, 4.5 V ≤ V DD2 ≤ 5.5 V; all minimum/maximum specifications apply over the entire recommended operating range, unless otherwise noted; all typical specifications are at T A = 25°C, V DD1 = V DD2 = 5 V; this does not apply to the ADuM1200W and ADuM1201W automotive grade products.

Table 1.

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 t PHL propagation delay is measured from the 50% level of the falling edge of the V Ix signal to the 50% level of the falling edge of the V Ox signal. t PLH propagation delay is measured from the 50% level of the rising edge of the V Ix signal to the 50% level of the rising edge of the V Ox signal.

5 t PSK is the magnitude of the worst-case difference in t PHL and/or t PLH 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 V O > 0.8 V DD2 . CM L is the maximum common-mode voltage slew rate that can be sustained while maintaining V O < 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 as a function of data rate for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating per-channel supply current for a given data rate.

Ambient temperature = 25°C, unless otherwise noted.
