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. 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.

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.
