The reference built inside has good specification. With 2.5 volts as the reference and a 4.5 ppm per deg C the change is 11 micro volts per degree in the reference. The step size of a 12 bit ADC with 2.5 volt ref is 610 micro volts. So about 30 degrees change in temperature inside gadget using this device can with stand good accuracy.
