Data Sheet

ADuM3400/ADuM3401/ADuM3402

¹The 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 can 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 V_DD1and V_DD2supply currents as a function of data rate for ADuM3400/ADuM3401/ADuM3402 channel configurations.

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

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

⁴t_PHLpropagation delay is measured from the 50% level of the falling edge of the V_Ixsignal to the 50% level of the falling edge of the V_Oxsignal. t_PLHpropagation delay is

measured from the 50% level of the rising edge of the V_Ixsignal to the 50% level of the rising edge of the V_Oxsignal.

⁵t_PSKis the magnitude of the worst-case difference in t_PHLor t_PLHthat is measured between units at the same operating temperature, supply voltages, and output load

within the recommended operating conditions.

⁶Codirectional 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.

⁷CM_His the maximum common-mode voltage slew rate that can be sustained while maintaining V_O> 0.8 V_DD2. CM_Lis 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.

⁸Dynamic 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.
