LIS3DH Internal Pull-Ups

Hello

At the LIS3DH Datasheet is stated that there are internal Pull-Ups at all SPI pins of the LIS3DH. How much is the approximate value of the pull-up resistors? According to my experience, with the CS tied high, the SDO pin does really have a pull-up capacitor, but not SPC. Is the datasheet correct? I noticed that at the new LIS2DH, the pull-up is present just at the SDO.

Hello Luis,

Yes you are right, please find on the attached datasheet (page 18) an application hint that might be able to clarify the sensor functioning.

Please do let me know if you need any further information,

Thank you very much,

Thiago
