LIS3DH Power Consuption

Hi!

I am not getting anywhere near the Power Consuption specifications. I see a minimum power off 100uA, and no way to cut it down.

According to documentation this device start in Power Down until any register is manipulated, and in that conditions, we see 100uA.

Anybody idea what could be going on?

I found this comment:

''I am betting that the LIS3DSH is like the LIS3DH and that the I2C address select pin has an internal Pull Up resistor.  Since you are grounding that pin you have an extra current flowing through that pin.  We confirmed this on the LIS3DH.''

Could this be the problem?
