1.3 Test Circuit
The circuit used for most DC and AC tests is shown in
Figure 1-1. This circuit can independently set V_CM and
V_OUT; see Equation 1-1. Note that V_CM is not the
circuit’s common mode voltage ((V_P + V_M)/2), and that
V_OST includes V_OS plus the effects (on the input offset
error, V_OST) of temperature, CMRR, PSRR and A_OL.
EQUATION 1-1:
G_DM = R_F ⁄ R_G
V_CM = (V_P + V_DD ⁄ 2) ⁄ 2
V_OST = V_IN– – V_IN+
V_OUT = (V_DD ⁄ 2) + (V_P – V_M) + V_OST(1 + G_DM)
Where:
G_DM = Differential Mode Gain
V_CM = Op Amp’s Common Mode
Input Voltage
V_OST = Op Amp’s Total Input Offset
