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
Ω
resistor in series with a 10μF
capacitor.

Turn-On Time
The X60008 devices have ultra-low supply current and
thus the time to bias up internal circuitry to final values
will be longer than with higher power references. Nor-
mal turn-on time is typically 7ms. This is shown in the
graph, Figure 4. Since devices can vary in supply cur-
rent 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 conver-
sions 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 multi-
plied by 10
6
to yield ppm/°C. This is the “Box” method.
