The following provide additional information about some of the
parameters cited. For additional information, visit the Allegro
Web site at www.allegromicro.com.
Applied Magnetic Field, B
diff
  The differential magnetic flux
density, which is calculated as the arithmetic difference of the
flux densities observed by each of the two Hall elements. f
Bdiff
is
the input signal frequency.
Output Off Switchpoint (Operate Point), B
OP
  The value of
increasing differential magnetic flux density at which the device
output switches from low to high (A1421) or high to low (A1422
and A1423).
Output On Switchpoint (Release Point), B
RP
  The value of
decreasing differential magnetic flux density at which the device
output switches from high to low (A1421) or from low to high
(A1422 and A1423).
Power-On Time, t
PO
  The time needed by the device, after
power is applied, to initialize all circuitry necessary for proper
operation.
Settling Time, t
Settling
  The time required by the device, after
t
PO
, and after a valid magnetic signal has been applied, to
provide proper output transitions. Settling time is a function of
magnetic offset, offset polarity, signal phase, signal frequency,
and signal amplitude.
Supply Current (on), I
CC(on)
  The current draw of the device
with the output transitor is turned on.
Supply Current (off), I
CC(off)
  The current draw of the device
with the output transitor is turned off.
Response Time, t
Response
  The total time required for generating
zero-crossing output transitions after initialization (the sum of
Power-on Time and Settling Time).
