package Op Amp evaluation board. It should be used in
conjunction with the appropriate data sheet which contains
full technical details on the device specification and
operation. This evaluation board is offered as a convenience
for the customers interested in performing their own
engineering characterization and performance assessment.
The evaluation board provides a 50 W controlled impedance
environment. The evaluation board is designed to facilitate
a quick evaluation of the device. The default populated
evaluation board will have a gain of two.

implemented in two layers (Figure 1, Evaluation Board
Lay−up). The first layer is the 1.0 oz copper ground plane,
where a portion of the ground plane is cut out to mount the
device. The FR4 dielectric material is placed between the
first and second layer. The second layer contains the rest of
the components and primary signal traces.
evaluation board has versatile loading options for the op
amp through C9, R10, and R11 depending on the user’s
preference it can be configured as capacitive load, series
resistance load, parallel resistance load, etc.
