Definitions of Dynamic Response Characteristics
Propagation delay (t
PROP
).
The time required for the device
output to reflect a change in the primary current signal. Propaga-
tion delay is attributed to inductive loading within the linear IC
package, as well as in the inductive loop formed by the primary
conductor geometry. Propagation delay can be considered as a
fixed time offset and may be compensated.

Rise Time, t

t
Rise time (t
r
).
The time interval between a) when the device
reaches 10% of its full scale value, and b) when it reaches 90%
of its full scale value. The rise time to a step response is used to
derive the bandwidth of the device, in which (–3 dB) = 0.35 / t
r
.
Both t
r
and t
RESPONSE
are detrimentally affected by eddy current
losses observed in the conductive IC ground plane.
Response time (t
RESPONSE
).
The time interval between a) when
the primary current signal reaches 90% of its final value, and b)
when the device reaches 90% of its output corresponding to the
applied current.
