Propagation delay (t
rent signal. Propagation 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.
Response time (t
final value, and b) when the device reaches 90% of its output corresponding to the applied current.
Rise time (t
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 ƒ(–3 dB) = 0.35 / t
