LIS3DH high pass filter cutoff frequency for 1344Hz

ADani · ‎2022-03-13

Hello,

I'm working on LIS3DH sensor and trying to configure the HPF in high resolution mode. I couldn't find the cutoff frequency for 1344Hz ODR neither in the datasheet nor application note. Can anyone help me regarding this?

Hi @ADani ,

since the high performance/normal mode 1344Hz ODR shares part of the electric circuit with the Low-power mode (5.376 kHz), you can refer to the Table 11 of the Application Note AN3308:

Hi @Eleon BORLINI

Thanks for your reply. But, I would like to have more clarity on this. The cutoff of 1.6KHz is way less than 5kHz, and 1.3KHz is closer to 1.6kHz then how can I choose 5.3kHz cutoff for 1.3kHz?

Can you explain the "ODR shares part of electric circuit with low power mode"? Can you point exactly where this is specified in the datasheet or application note? I couldn't find this in the datasheet.
