LIS3MDL: Can I use 3v3 for the vddio. Will the voltage of I2C also be 3v3?

Hello,

I want to use the LIS3MDL for a project. I am using a microcontroller with I2C lines at 3V3. In the datasheet there is mentioned that the typical voltage for VDDIO is 1V8 but with a range up to VDD +0.1 V. I will power the device (VDD) with 3V3. If I also use 3V3 for the VDDIO will the sensor communicate at 3V3 or 1V8.

Thank you in advance

    Welcome, @Noah Verstraete​, to the community!

    Correct, you can operate VDDIO with the same voltage as VDD, if VDD=3.3V.

    The sensor always communicates on the level of VDDIO, in this case with 3.3V.

    Does that answer your question?
