Hello!
Is the default setting of the LMP91200 to always have Vcm be 1/2 of Vref? The datasheet is not very clear on this, especially since there is a legacy option to select Vcm in 1/8 steps.
I would appreciate if you could confirm!

Lindsey,
Yes, the default setting is for VCM to be at 1/2 of VREF. The primary use case for this part is to be a standalone PH AFE part that does not need to be configured. The data sheet does not cover programming or changes in this part.
