Figure 3 shows the evaluation board schematic. Enables quick breadboarding/prototyping Selectable gain of 1, 2, or 3 Edge-mounted SMA connector provisions Easy connection to test equipment and other circuits GENERAL DESCRIPTION The 16-lead, 3 mm × 3 mm lead frame chip scale package (LFCSP) evaluation board is designed to aid in the evaluation of single, high speed, selectable gain differential amplifiers. It has the flexibility to choose between a gain of 1, 2, or 3. 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 differential amplifier circuits, which minimizes risk and reduces time to market. The evaluation board supports any of Analog Devices, Inc., single, high speed differential amplifiers in 3 mm × 3 mm LFCSP packages. 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. The board ground plane, component placement, and power supply bypassing have been optimized for maximum circuit flexibility and performance. The evaluation board uses a variety of surfacemount technology (SMT) component case sizes: 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. NOTES 1.
