load capacitances above .001μF the noise reduction
network shown in fig. 3 is recommended. This network
reduces noise sig-nificantly over the full bandwidth. As
shown in fig. 2, noise is reduced to less than 40μVp-p
from 1Hz to 1MHz using this network with a .01μF
capacitor and a 2k
resistor in series with a 10μF
capacitor.

Figure 3.
Turn-On Time
The X60003x-41 device has ultra-low supply current
and thus the time to bias up internal circuitry to final
values will be longer than with higher power refer-
ences. Normal turn-on time is typically 7ms. This is
shown in the graph, Figure 4. Since devices can vary
in supply current down to 300nA, turn-on time can last
up to about 12ms. Care should be taken in system
design to include this delay before measurements or
conversions are started.
Figure 4.
Temperature Coefficient
The limits stated for temperature coefficient (tempco)
are governed by the method of measurement. The
overwhelming standard for specifying the temperature
drift of a reference is to measure the reference voltage
at two temperatures, take the total variation, (V
HIGH
-
V
LOW
), and divide by the temperature extremes of
measurement (T
HIGH
- T
LOW
). The result is divided
by the nominal reference voltage (at T = 25°C) and
multiplied by 10
6
to yield ppm/°C. This is the “Box”
method for determining temperature coefficient.
