LSM6DS, ASM330, ISM330 digitization multiplexing and filtering

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.
