Figure 1-8 shows VE vs. VCM, as well as a linear fit line (VE_LIN) based on VOS and CMRR. The op amp is in standard conditions ( ΔVOUT =0, VDM =0, etc.). VCM is swept from VIVL to VIVH. The test circuit is in Section 1.4.1 “Input Offset Test Circuit” and VE is calculated using Equation 1-4. FIGURE 1-8: Input Offset Error vs. Common Mode Input Voltage. Based on the measured VE data, we obtain the following linear fit: EQUATION 1-6: The remaining error ( ΔVE) is described by the Common Mode Non-Linearity spec: EQUATION 1-7: The same common mode behavior applies to VE when VREF is swept, instead of VCM, since both input stages are designed the same: EQUATION 1-8: 1.5.3 DIFFERENTIAL GAIN ERROR AND NON-LINEARITY The differential errors are extracted from differential gain measurements (see Section 1.4.2 “Differential Gain Test Circuit”), based on Equation 1-2. These errors are the differential gain error (gE) and the input offset error (VE, which changes non-linearly with VDM): EQUATION 1-9: These errors are adjusted for the expected output, then referred back to the input, giving the differential input error (VED) as a function of VDM: EQUATION 1-10: V E V M V REF – G DM 1gE + () --------------------------------- = Where: PSRR , CMRR and A OL are in units of V/V ΔT A is in units of °C VDM =0 V E V OS ΔV DD ΔV SS – PSRR --------------------------------- ΔV CM CMRR ----------------- ΔV REF CMRR ----------------- ++ + = ΔV OUT A OL ----------------- ΔT A ΔV OS ΔT A ------------- ⋅ ++ V1 V3 VE, VE_LIN (V) VCM (V) VIVL VIVH VDD/2 V2 VE_LIN VE ΔVE Where: V E_LIN V OS V CM V DD 2 ⁄ – CMRR ----------------------------------- + = V OS V 2 = 1 CMRR ----------------- V 3 V 1 – V IV H V IVL – ------------------------------ = Where: INL CM max ΔV E V IVH V IV L – ------------------------------ = ΔV E V E V E_LIN – = V E_LIN V OS V REF V DD 2 ⁄ – CMRR ------------------------------------- + = INL CM max ΔV E V IVH V IVL – ------------------------------ = G DM 1R F RG ⁄ + = V M G DM 1gE + () V DM V + E () = V ED V M G DM ------------V DM – = |
