AC ELECTRICAL CHARACTERISTICS TEMPERATURE CHARACTERISTICS 1.1 Test Circuits The test circuits used for the DC and AC tests are shown in Figure 1-1 and Figure 1-1. The bypass capacitors are laid out according to the rules discussed in Section 4.6 “PCB Surface Leakage”. FIGURE 1-1: AC and DC Test Circuit for Most Non-Inverting Gain Conditions. FIGURE 1-2: AC and DC Test Circuit for Most Inverting Gain Conditions. Electrical Characteristics: Unless otherwise indicated, T A = +25°C, VDD = +1.8 to 5.5V, VSS = GND, VCM = VDD/2, VOUT ≈ VDD/2, RL = 100 kΩ to VDD/2 and CL = 60 pF.
