Output supply current values are with no output load present. See Figure 5 and Figure 6 for information on supply current variation with logic signal frequency. See
the Power Consumption section for guidance on calculating the input and output supply currents for a given data rate and output load.
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.

t
PHL
is measured from the 50% level of the falling edge of the V
I
signal to the 50% level of the falling edge of the V
O
signal. t
PLH
is measured from the 50% level of the
rising edge of the V
I
signal to the 50% level of the rising edge of the V
O
signal.

Because the input thresholds of the ADuM1100 are at voltages other than the 50% level of typical input signals, the measured propagation delay and pulse width
distortion can be affected by slow input rise/fall times. See the Propagation Delay-Related Parameters section and Figure 14 through Figure 18 for information on the
impact of given input rise/fall times on these parameters.
6
Pulse width distortion change vs. temperature is the absolute value of the change in pulse width distortion for a 1°C change in operating temperature.
7
t
PSK1
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 and output load within the
recommended operating conditions. t
PSK2
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.
8
CM
H
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 edges. The transient magnitude is the range
over which the common mode is slewed.
9
Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 5 and Figure 6 for information on
supply current variation with logic signal frequency. See the Power Consumption section for guidance on calculating the input and output supply currents for a given
data rate and output load.
