The EB-D24CP44-2Z 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-D24CP44-2Z evaluation board supports any of Analog Devices, Inc., dual high speed differential amplifiers in 4 mm × 4 mm lead frame chip scale packages (LFCSP). Figure 1 shows the component side and circuit side of the evaluation board. Figure 2 shows the evaluation board schematic. 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. 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, 0805, and 7343. Figure 3 and Figure 5 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 4 and Figure 6. 08142-006 DIGITAL PICTURE OF THE EVALUATION BOARD COMPONENT SIDE CIRCUIT SIDE NOTES 1.
