Note 1: The VIP input is treated as the Common-mode input (e.g., for CMRR). VDM =(VIP –VIM).

2: Set by design and characterization. VOS is screened in production (see Appendix B: “Offset Test

Screens”).

3: See the discussion in Section 1.6.2, Input Offset Related Errors.

4: See Section 1.6, Explanation of DC Error Specifications.
