1.3 Test Circuit
CF 6.8 pF The circuit used for most DC and AC tests is shown in Figure 1-1. This circuit can independently set VCM and V RG R OUT; see Equation 1-1. Note that VCM is not the F circuit’s common mode voltage ((V 100 k 100 k P + VM)/2), and that V V V P DD/2 OST includes VOS plus the effects (on the input offset V error, V DD OST) of temperature, CMRR, PSRR and AOL.
