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.
