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. EQUATION 1-1: FIGURE 1-1: AC and DC Test Circuit for Most Specifications. TABLE 1-2: AC ELECTRICAL SPECIFICATIONS Electrical Characteristics: Unless otherwise indicated, TA = 25°C, VDD = +5.0V, VSS = GND, VCM = VSS, VOUT ≈ VDD/2, VL = VDD/2, RL = 10 kΩ to VL and CL = 60 pF (refer to Figure 1-1).
