ISL60002
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
4ms. This is shown in Figure 119. 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, (VHIGH – VLOW), and divide by the temperature
extremes of measurement (THIGH – TLOW). The result is divided
by the nominal reference voltage (at T = +25°C) and multiplied
by 106 to yield ppm/°C. This is the “Box” method for specifying
temperature coefficient.
