VCM = (VIP + VIM)/2, VDM = (VIP – VIM) and GDM = 1 + RF/RG.
For Design Guidance only; not tested.
These specifications apply to the VIP, VIM input pair (use VCM) and to the VREF, VFG input pair (use VREF instead).
This specification applies to the VIP, VIM, VREF and VFG pins individually.
Figures 2-52 and 2-53 show the VIVL, VIVH, VDML and VDMH variation over temperature.
See Section 1.5 “Explanation of DC Error Specifications”.
