Note 1. Leakage current may increase if digital input voltages are not close to VDD (logic high) or GND (logic low).

Note 2. Standby current is an extra current that is drawn only in the normal mode (MODE=11)

Note 3. Activating EEPROM (EON=010 or 101) turns on internal regulator. To minimize current consumption the EEPROM should be kept

inactive (EON=000) in any other time when not used.

Note 4. Current consumption values are from forced mode at measurement rate 1Hz.
