Ad7124-8 with high load cell excitation

Hello,

I need to interface a load cell with very low mv/v output and therefore I am plannining to use a 10v excitation voltage.I  am considering two options in order to divide the refin voltage(connected to excitation and ground) down to ad7124 specs:

a. Precision resistors voltage divider

b. Precision op amp voltage divider arrangement.

 

I will correct the voltage difference in software.

 

1. Should I prefer one option over the other?

2. If non is advisable is there another option or I am better off with another chip?

Thanks!
