Figure 3 shows the evaluation board schematic. Enables quick breadboarding/prototyping User-defined circuit configuration Edge-mounted SMA connector provisions Easy connection to test equipment and other circuits The 4-layer evaluation board accepts edge-mounted Subminiature Version A (SMA) connectors on both inputs and outputs, which allows efficient and quick connection to test equipment or other circuitry. GENERAL DESCRIPTION The 8-lead standard small outline package (SOIC), with a dedicated feedback pin and an exposed paddle, evaluation board is designed to aid in the evaluation of single, high speed operational amplifiers. The evaluation board is a bare board (that is, there are no components soldered to the board) that enables users to quickly prototype a variety of operational amplifier circuits, which minimizes risk and reduces time to market. The evaluation board supports any of the Analog Devices, Inc., single, high speed operational amplifiers in an 8-lead SOIC package with a dedicated feedback pin and an exposed paddle. The board ground plane, component placement, and power supply bypassing are optimized for maximum circuit flexibility and performance. The evaluation board uses a variety of surfacemount technology (SMT) component case sizes: 0402, 0508, 0603, and 7343. Figure 4 and Figure 6 show the evaluation board assembly drawings. The metal layout pattern for connecting the board to the op amp and to the supporting circuitry is shown in Figure 5 and Figure 7. 08787-001 08787-002 EVALUATION BOARD COMPONENT SIDE AND CIRCUIT SIDE DIAGRAMS Figure 2.

The first way is to place the gain resister in the R1 location and uses a 0 Ω for the R2 location to short to ground. The second way is to place the gain resister between the first pad of R1 and ground, without using a second resistor (see Figure 8). Figure 8.
