Full power-down mode is activated by turning off the supply or by asserting PD to 1. See Figure 55 and
Figure 56. The device can be resumed from full power down by either turning on the power supply or by
de-asserting the PD pin. The first two conversions produce inaccurate results because during this period the
device loads its trim values to ensure the specified accuracy.
If an internal reference is used (with a 1-F capacitor installed between the REFOUT and REFM pins), the total
resume time (td18) is 25 ms. After the first two conversions, td17 (4 ms) is required for the trimmed internal
reference voltage to settle to the specified accuracy. Only then the converted results match the specified
accuracy.
