LTC2421 settings


Am using LTC2421IMS#PBF in my design for a low voltage ADC application.

I have doubt with the below connections:

- FSSET can be connected directly to voltage? (0.95V in design)

- ZSSET can be connected to the ground? (to set the range from 0 to 0.95V)

The unused pin (aux input) can be left floating or should it be grounded?

Below is the circuit connection :

Can anyone please help me with some inputs.

Thanks & Regards,
