AD8362 EVALUATION BOARD
The AD8362 evaluation board provides for a number of dif-
ferent operating modes and configurations, including many
described in this data sheet. The measurement mode is set up
by positioning SW2 as shown in Figure 67. The AD8362 can be
operated in controller mode by applying the setpoint voltage to
the VSET connector, and flipping SW2 to its alternate position.
The internal voltage reference is used for the target voltage when
SW1 is in the position shown in Figure 67. This voltage may
optionally be reduced via a voltage divider implemented with
R4 and R5, with LK1 in place, and SW1 switched to its alternate
position. Alternatively, an external target voltage may be used

with SW1 switched to its alternate position, LK1 removed, and
the external target voltage applied to the VTGT connector.
In measurement mode, the slope of the response at VOUT may
be increased by using a voltage divider implemented with resis-
tors in Position R17 and Position R9, and with SW2 switched to
its alternate position.
The AD8362 is powered up with SW3 in the position shown in
Figure 67 and connector PWDN open. The part can be powered
down by either connecting a logic high voltage to a connector,
PWDN, with SW3 in the position, or by switching SW3 to its
alternate position.
