The evaluation board is a bare board that enables users to quickly prototype a Figure 1. Evaluation Board, Component Side variety of single op amp circuits, which minimizes risk and reduces time to market. Figure 1 shows the component side of the bare evaluation board. Figure 2 shows the circuit side of the bare evaluation board. The 6-layer evaluation board accepts SMA edge-mounted connectors on the inputs and outputs for efficient connection to test equipment or other circuitry. The ground plane, component placement, and supply bypassing minimize parasitic inductance and capacitance. The evaluation board components are primarily SMT 0603 case size, with the exception of the electrolytic bypass capacitors (C1 and C2), which are 3528 case size. Figure 2. Evaluation Board, Circuit Side Figure 3 shows the evaluation board schematic and Figure 4 through Figure 6 show the interface schematics. The printed circuit board (PCB) assembly drawings are shown in Figure 7 and Figure 9. See Figure 8 and Figure 10 for the PCB layout patterns. The layout pattern for the PCB is shown in Figure 8 and Figure 10. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. Rev.
