LSM6DS, ASM330, ISM330 digitization multiplexing and filtering

[fgs]

Hello,

Could you please confirm that in LSM6DS, as in ASM330, as in ISM330, the low pass gyroscope filtering LPF2 cannot be bypassed and is only driven by ODR_G (no "enable" flag is available for this filtering stage) ?  

Furthermore, the block diagrams in the corresponding datasheets suggest that a single ADC (ADC1) is used to digitize the three axes of the gyroscope. Could you please confirm that digitization is indeed multiplexed in these products ?

Thank you by advance for your help.

Hi @fgs ,

The LPF2 is not configurable and the cutoff frequency depends on the ODR_G.

There are 3 different ADCs to digitize the three axes of the gyroscope.
