Figure 3 shows the evaluation board schematic. FEATURES Enables quick breadboarding/prototyping Selectable gain of 1, 2, or 3 Edge-mounted SMA connector provisions Easy connection to test equipment and other circuits Two independent circuits enhance flexibility The 4-layer evaluation board accepts edge-mounted SMA connectors on both inputs and outputs, which allows efficient and quick connection to test equipment or other circuitry. GENERAL DESCRIPTION The EB-D24CP44SG-2Z is designed to aid in the evaluation of dual high speed, selectable gain differential amplifiers. It has the flexibility to choose between the gain of 1, 2, or 3. The EB-D24CP44SG-2Z 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 EB-D24CP44SG-2Z evaluation board supports any of Analog Devices, Inc., dual high speed differential amplifiers in 4 mm × 4 mm lead frame chip scale packages (LFCSP). 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 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. NOTES 1.
