What is the data rate accuracy of the LSM6DS33? For example, if configured at 12.5 Hz, what is the time drift in ppm of the data output?

Hi @MLi.4 ,

please note first that the LSM6DS33. These are results coming from characterization data on a representative samples of a production lot. The jitter is moreover below 1us for ODR = 12.5Hz.

My suggestion is however to directly check your actual ODR by plotting with an oscilloscope the DRDY signals (INT1_ DRDY_G and INT1_ DRDY_XL bits of INT1_CTRL (0Dh) register, see datasheet p. 45) routed on a physical INT pin (e.g. INT1).
