ADuM1100
APPLICATION INFORMATION
PC BOARD LAYOUT
The ADuM1100 digital isolator requires no external interface
circuitry for the logic interfaces. A bypass capacitor is recom-
mended at the input and output supply pins. The input bypass
capacitor can conveniently be connected between Pin 3 and
Pin 4 (see Figure 13). Alternatively, the bypass capacitor can be
located between Pin 1 and Pin 4. The output bypass capacitor
can be connected between Pin 7 and Pin 8 or Pin 5 and Pin 8.
The capacitor value should be between 0.01 μF and 0.1 μF. The
total lead length between both ends of the capacitor and the
power supply pins should not exceed 20 mm.

PROPAGATION DELAY-RELATED PARAMETERS
Propagation delay time describes the length of time it takes for
a logic signal to propagate through a component. Propagation
delay time to logic low output and propagation delay time to
logic high output refer to the duration between an input
signal transition and the respective output signal transition
(see Figure 14).
Data Sheet
Pulse width distortion is the maximum difference between
t PLH and t PHL and provides an indication of how accurately the
input signal’s timing is preserved in the component’s output
signal. Propagation delay skew is the difference between the
minimum and maximum propagation delay values among
multiple ADuM1100 components operated at the same
operating temperature and having the same output load.
Depending on the input signal rise/fall time, the measured
propagation delay based on the input 50% level can vary from
the true propagation delay of the component (as measured from
its input switching threshold). This is because the input threshold,
as is the case with commonly used optocouplers, is at a different
voltage level than the 50% point of typical input signals. This
propagation delay difference is given by
Δ LH = t ′ PLH ? t PLH = ( t R /0.8 V I )(0.5 V I ? V ITH (L-H) )
Δ HL = t ′ PHL ? t PHL = ( t F /0.8 V I )(0.5 V I ? V ITH (H-L) )
where:
t PLH and t PHL are the propagation delays as measured from the
input 50% level.
t’ PLH and t’ PHL are the propagation delays as measured from the
input switching thresholds.
t R and t F are the input 10% to 90% rise/fall times.
V I is the amplitude of the input signal (0 V to V I levels assumed).
V ITH (L– H) and V ITH (H–L) are the input switching thresholds.
