AD8476 Differential Amplifier Evaluation Board for
8-Lead MSOP Package
FEATURES
Enables quick evaluation of AD8476
Enables quick breadboarding/prototyping
Allows for various circuit configurations
Through-hole connector provisions
Easy connection to test equipment and other circuits
RoHS compliant
GENERAL DESCRIPTION
The AD8476-EVALZ makes it easy for designers to obtain quick
performance results for their particular application circuit using
the AD8476 low power, fully-differential G = 1 amplifier.
The board layout is flexible enough to allow for different circuit
configurations, including options for single-ended or differ-
ential inputs, and space for output loading and filtering. Most
resistors and capacitors use 0603 packages.
The 4-layer evaluation board accepts through-hole SMA or
SMB connectors on inputs, outputs, and VOCM, which allows
an efficient and quick connection to test equipment or other
circuitry. There is also room for 2-pin BERG headers at the
inputs and outputs for connection to differential probes, and
test points at supply and ground pins. The board ground plane,
component placement, and power supply bypassing have been
optimized for maximum circuit flexibility and performance.
Figure 1 and Figure 2 show the component side and circuit side
of the evaluation board. Figure 3 shows the evaluation board
schematic.
Figure 4 shows the evaluation board assembly drawing.
The metal layout pattern for connecting the board to the op
amp and to the supporting circuitry is shown in Figure 5 and
Figure 6.
The board accommodates the AD8476 differential amplifier
in an 8-lead MSOP. The AD8476 data sheet for this device
should be consulted in conjunction with this evaluation board
user guide.
