Notes
1. The quoted values of
V
ref
are based on a constant current I
Z
. Two factors can cause
V
ref
to change with I
Z
, namely
the differential resistance r
dif
and the temperature coefficient S
Z
.
a) Each change of I
Z
can result in a maximum change of
V
ref
as follows:
V
ref
(mV) =
I
Z
(mA)
15
taking into account that r
dif
is max. 15
.
b) The temperature coefficient of the reference voltage S
Z
is also a function of I
Z
. However, for these reference
diodes S
Z
varies max.
0.05 mV/K or
0.001%/K when I
Z
is between 6 and 10 mA, so this effect can be neglected
in practice for these types.
2. The temperature coefficient of the reference voltage is obtained from the following formula:
