Turn-On Time
The ISL60002 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 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 specifying temperature
coefficient.
