EVALUATION BOARD
Evaluation boards for the AD8180R and AD8182R are available
which have been carefully laid out and tested to demonstrate the
specified high speed performance of the devices. Figure 26 and
Figure 27 show the schematics of the AD8180 and AD8182
evaluation boards respectively. For ordering information, please
refer to the Ordering Guide.
Because the footprint of the AD8180 fits directly on to that of
the AD8182, one board layout can be used for both devices. In the
case of the AD8180, only the top half of the board is populated.
Figure 28 shows the silkscreen of the component side and Fig-
ure 30 shows the silkscreen of the solder side. Figures 29 and 31
show the layout of the component side and solder side respectively.

The evaluation board is provided with 49.9
tors on all inputs. This is to allow the performance to be evalu-
ated at very high frequencies where 50
popular. To use the evaluation board in video applications, the
termination resistors should be replaced with 75
The multiplexer outputs are loaded with 4.99 k resistors. In
order to avoid large gain errors, these load resistors should be
greater than or equal to 1 k . For connection to external instru-
ments, oscilloscope scope probe adapters are provided. This
allows direct connection of FET probes to the board. For verifi-
cation of data sheet specifications, use of FET probes with a
bandwidth > 1 GHz is recommended because of their low input
capacitance. The probe adapters used on the board have the
same footprint as SMA, SMB and SMC type connectors allow-
ing easy replacement if necessary.
