LIS2DH power consumption with 1 axis enabled?

[eggs]

We're evaluating the LIS2DH (and -DE) for a very low-power project, and every uA is precious. We only need readings from one axis, so I am curious as to whether disabling the other two axes would result in power savings. I've tried measuring it here on my desk, but sadly, my multimeter isn't sufficiently accurate down in the single-digit-uA range.

So my question is: does disabling one or more axes reduce the power consumption?

Hi @Community member​ , the answer to your question is basically no, i.e. the difference in terms of current consumption between a full-axis enabled configuration and a single axis configuration is negligible. The fact is that the internal electronics "stops" the data of the single axis just before the muxing with the other axis (ADC running and so on), but the output tri-state buffer is nevertheless active for the enabled axis.
