Characteristics Definitions
(1) Sensitivity V
h
[mV/A], offset voltage V
of
[V]
Sensitivity is defined as the slope of the approximate straight line calculated by the least square method,
using the data of VOUT voltage (V
OUT
) when the primary current (I
IN
) is swept within the range of linear
sensing range (I
NS
). Offset voltage is defined as the intercept of the approximate straight line above.
(2) Linearity error ρ [%F.S.]
Linearity error is defined as the ratio of the maximum error voltage (V
d
) to the full scale (F.S.), where V
d
is
the maximum difference between the VOUT voltage (V
OUT
) and the approximate straight line calculated in
the sensitivity and offset voltage definition. Definition formula is shown in below:
ρ = Vd / F.S. × 100
NOTE) Full scale (F.S.) is defined by the multiplication of the linear sensing range and sensitivity (See
Figure 5).
Figure 5. Output characteristics of CQ-2063
(3) Ratiometric error of sensitivity V
h-R
[%] and ratiometric error of offset voltage V
of-R
[%]
Output of CQ-2063 is ratiometric, which means the values of sensitivity (V
h
) and offset voltage (V
of
) are
proportional to the supply voltage (V
DD
). Ratiometric error is defined as the difference between the V
h
(or
V
of
) and ideal V
h
(or V
of
) when the V
DD
is changed from 5.0V to V
DD1
(4.5V<V
DD1
<5.5V). Definition formula is
shown in below:
V
h-R
= 100 × {(V
h
(V
DD

DD1
) / V
h
(V
DD
= 5V)) − (V
DD1

V

(V

DD1
) / V
of
(V
DD

DD1
/ 5)} / (V
DD1
/ 5)
(4) Temperature drift of sensitivity V
h-d
[%]
Temperature drift of sensitivity is defined as the drift ratio of the sensitivity (V
h
) at T
a
=T
a1
(−40C<T
a1
<90C)
to the V
h
at T
a
=35C, and calculated from the formula below:
V
h-d
= 100 × (V
h
(T
a1
) / V
h
(35C) − 1)
Maximum temperature drift of sensitivity (V
h-dmax
) is defined as the maximum value of |V
h-d
| through the
defined temperature range.
Reference data of the temperature drift of sensitivity of CQ-2063 is shown in Figure 6.

(5) Temperature drift of offset voltage V
of-d
[mV]
Temperature drift of offset voltage is defined as the drift value between the offset voltage (V
of
) at T
a
=T
a1
(−40C<T
a1
<90C) and the V
of
at T
a
=35C, and calculated from the formula below:
V
of-d
= V
of
(T
a
= T
a1
) − V
of
(T
a
= 35C)
Maximum temperature drift of offset voltage (V
of-dmax
) is defined as the maximum value of |V
of-d
| through the
defined temperature range.
Reference data of the temperature drift of offset voltage of CQ-2063 is shown in Figure 7.

(6) Rise response time t
r
[μs] and fall response time t
f
[μs]
Rise response time (or fall response time) is defined as the time delay from the 90% (or 10%) of input
primary current (I
IN
) to the 90% (or 10%) of the VOUT voltage (V
OUT
) under the pulse input of primary
current (see Figure 8.)
