Test Circuits
The circuit used for most DC and AC tests is shown in
Figure 1-2. This circuit can independently set VCM and
VOUT; see Equation 1-1. Note that VCM is not the
circuit’s common mode voltage ((VP +VM)/2), and that
VOST includes VOS plus the effects (on the input offset
error, VOST) of temperature, CMRR, PSRR and AOL.
