Evaluation Board for Dual High Speed Differential Amplifiers
FEATURES
Enables quick breadboarding/prototyping
User-defined circuit configuration
Edge-mounted SMA connector provisions
Easy connection to test equipment and other circuits
Two independent circuits enhance flexibility
GENERAL DESCRIPTION
The EB-D24CP44-2Z is designed, to aid in the evaluation of
dual high speed differential amplifiers. 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.
