HAH1DR 200-S
PERFORMANCES PARAMETERS DEFINITIONS
Output noise voltage:
The output voltage noise is the result of the noise floor of the
Hall elements and the linear I_C amplifier gain.
Magnetic offset:
The magnetic offset is the consequence of an over-current on
the primary side. It’s defined after an excursion of I_{P max}.
Linearity:
The maximum positive or negative discrepancy with a reference
straight line V_OUT = f (I_P).
Unit: linearity (%) expressed with full scale of I_{P max}.
Linearity is measured on cycle + I_P, O, - I_P, O, + I_P without
magnetic offset (average values used).

Sensitivity:
The Transducer’s sensitivity G is the slope of the straight line
V_out = f (I_P), it must establish the relation:
V_out (I_P) = V_C/5 (G x I_P + 2.5) (*)
(*) For all symetrics transducers.
Offset with temperature:
The error of the offset in the operating temperature is the variation
of the offset in the temperature considered with the initial offset
at 25°C.
The offset variation I_OT is a maximum variation the offset in the
temperature range:
I_OT = I_OE max - I_OE min
The Offset drift TCI_OEAV is the I_OT value divided by the temperature
range.
Sensitivity with temperature:
The error of the sensitivity in the operating temperature is the
relative variation of sensitivity with the temperature considered
with the initial offset at 25°C.
The sensitivity variation G_T is the maximum variation (in ppm or
%) of the sensitivity in the temperature range:
G_T = (Sensitivity max - Sensitivity min) / Sensitivity at 25°C.
The sensitivity drift TCG_AV is the G_T value divided by the
temperature range.
Response time (delay time) t_r:
The time between the primary current signal and the output
signal reach at 90 % of its final value

Offset voltage @ I_P = 0 A:
Is the output voltage when the primary current is null. The ideal
value of V_O is V_C/2 at V_C = 5 V. So, the difference of V_O -V_C/2
is called the total offset voltage error. This offset error can be
attributed to the electrical offset (due to the resolution of the ASIC
quiescent voltage trimming), the magnetic offset, the thermal drift
and the thermal hysteresis.
