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 can be calculated as described in the section. See through for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See through for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1200 and ADuM1201 channel configurations. Power Consumption Power Consumption Figure 6 Figure 6 Figure 8 Figure 8 Figure 9 Figure 11 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 through for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See the section for guidance on calculating per-channel supply current for a given data rate. |
