Hello Team,
if SYSREF is not used can both pins be tied to ground?
Thanks and Best Regards,
Hans

Hi Hans,
It is recommended to tie SYSREFP to AVDD and SYSREFN to GND.
If the SYSREF is PDN, then both SYSREF pins will be in a high impedance state, but there will still be some time where the SYSREF inputs are active. In this case, you can float the SYSREF pins, as long as the SYSREF is PDN in the initial SPI configuration of the ADC.
Best Regards,
Dan
