Gyroscope power modes

In the LSM6DSO32, the gyroscope can be configured in four different operating modes:

power-down, low-power, normal mode and high-performance mode. The operating mode

selected depends on the value of the G_HM_MODE bit in CTRL7_G (16h). If G_HM_MODE

is set to '0', high-performance mode is valid for all ODRs (from 12.5 Hz up to 6.66 kHz).

To enable the low-power and normal mode, the G_HM_MODE bit has to be set to '1'. Low-

power mode is available for lower ODRs (12.5, 26, 52 Hz) while normal mode is available

for ODRs equal to 104 and 208 Hz.

Block diagrams of the accelerometer filters

In the LSM6DSO32, the filtering chain for the accelerometer part is composed of the

following:



Analog filter (anti-aliasing)



Digital filter (LPF1)



Composite filter

Details of the block diagram appear in the following figure.
