NOTES
All voltages are relative to their respective ground.

Output supply current values are with no output load present. The supply current drawn at a given signal frequency when an output load is present is given by
I

V

f

C
, where
I
is the unloaded output supply current,
f
is the input signal frequency, and
C
L
is the output load capacitance.
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
t
is measured from the 50% level of the falling edge of the V
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
signal to the 50% level of the rising edge of the V
signal.
6
Since 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
may be affected by slow input rise/fall times. See the Propagation Delay-Related Parameters
section and Figures 3 to 7 for information on the impact of given input
rise/fall times on these parameters.
7
Pulse width distortion change versus temperature is the absolute value of the change in pulse width distortion for a 1
°
C change in operating temperature.
8
t
is the magnitude of the worst-case difference in t
and/or t
that will be measured between units at the same operating temperature and output load within
the recommended operating conditions. t
is the magnitude of the worst-case difference in t
PHL
and/or t
PLH
that will be measured between units at the same operating
temperature, supply voltages, and output load within the recommended operating conditions.
9
CM
is the maximum common-mode voltage slew rate that can be sustained while maintaining V
> 0.8 V
. CM
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.

The dynamic power dissipation capacitance is given by
C
= (
I
– I
)/(
V
×
f
), where
i
= 1 or 2 and
f
is the input signal frequency.
