Could ADS8684 set sampling frequency by register? I didn't find description in the datasheet.

Also, could set the bandwidth of build-in LPF?

Hi Walsh

The sampling of the ADS8684 is controlled by the CSz signal. The device samples the input signal on the falling edge of the CSz signal. So you can control the sampling frequency by simply modifying the frequency of the CSz pulse. For more details, please refer to the "Device Interface" section, starting Page 32 of the datasheet.

The internal LPF has a fixed bandwidth.

Thanks
