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