BOARD DESCRIPTION
The AD8170 and AD8174 evaluation boards have been carefully
laid out and tested to demonstrate the specified high speed
performance of the devices. Figures 1 and 5 show the schematics
of the AD8170 and AD8174 evaluation boards respectively.
For ordering information, please refer to the Ordering Guide.
Figure 2 shows the silkscreen of the component side of the
solder side of the AD8170 evaluation board. Figures 3 and 4
show the layout of the component side and solder side respec-
tively. The silkscreens and layout of the AD8174 evaluation
board are shown in Figures 6–9.
Both evaluation boards ship with 75 W termination resistors on
their analog inputs and analog outputs. To use the evaluation
board in nonvideo applications where 50 W termination is more
popular, these resistors can be replaced with 50 W values. The
digital control pins are terminated with 50 W resistors to allow
easy connection to laboratory equipment.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
EVAL-AD8170EB/EVAL-AD8174EB features proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

EVAL-AD8170EB/EVAL-AD8174EB
The gain of the output current feedback op amp on both boards
has been set to +2. For other gains the two gain resistors can be
easily replaced. Refer to Table III of the AD8170/AD8174 data
sheet for appropriate values at gains other than +2.
For connection to external instruments, side-launched SMA
type connectors are provided. Space is also provided on the
board for the installation of SMB of SMC type connectors.
