    Current consumption depends on many factors, like power supply, data rates, power modes, window selection (for features computation in MLC), features selected in MLC, etc…

    Considering just the MLC part and excluding the sensor current consumption, MLC current consumption is usually limited to few uA or few tens of uA.

    Some examples of MLC configuration with current consumption estimation are available in the MLC application note (section 3).

    Taking the activity recognition application as example, with MLC_ODR = 26 Hz and a decision tree with around one hundred nodes, the MLC additional current consumption is just 4 uA (excluding sensor current consumption).
