Is the ODR of LSM6DS3 the same as sampling frequency?

Hello, I want to use a accelerometer which is LSM6DS3, and it's spec says that it's maximum ODR is 6600Hz.

So I want to know is the ODR the same as sampling frequency?

Or is it just out data rate? And is sampling frequency less than ODR?

If so, what's the maximum sampling frequency is this sensor chip?

Thanks!

    Hi @Ray Sun​ , in general, for ST sensors the internal sampling frequency (the ADC chain sampling, I mean) is higher (a multiple of) than the maximum ODR. If the sampling frequency were less than the ODR, you will get some identical consecutive data. Regards
