Definitions of Dynamic Response Characteristics
Power-On Time (t PO ). When the supply is ramped to its operat-
ing voltage, the device requires a finite time to power its internal
components before responding to an input magnetic field.
Power-On Time, t PO , is defined as the time it takes for the output
voltage to settle within ±10% of its steady state value under an
applied magnetic field, after the power supply has reached its
minimum specified operating voltage, V CC (min), as shown in the
chart at right.
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.

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
