BOARD DESCRIPTION
The AD8305 evaluation board has been carefully laid out and
tested to demonstrate the specified high speed performance of
the device. The schematic for the EVAL-AD8305EB is shown
in Figure 1. It can be configured for a wide variety of experi-
ments. The buffer gain is factory-set to unity, providing a slope
of 200 mV/decade, and the intercept is set to 1 nA. Table I
describes the various configuration options.
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-AD8305EB 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.
