The current consumption in power saving mode does not include the VREF pin output current. When
grounding the VREF pin to the AGND2 level using external resistance, a voltage of 1.18 to 1.32V is
generated at the VREF pin even in power saving mode. Therefore, the current indicated by the following
equation flows from the AV
consumption in power saving mode.
