Evaluation Board for Dual High Speed Selectable Gain Differential Amplifiers
(24-Lead, 4 mm × 4 mm LFCSP)
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
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).
Figure 1 and Figure 2 show the component side and circuit side
of the evaluation board. Figure 3 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, 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.
