APPLICATION INFORMATION
BUF11702 Demonstration Board
(Contact Factory)
The BUF11702 has an demonstration board that can be
mounted along with reference resistors and load
capacitors. This enables the BUF11702 to be used in its
own daughterboard in existing designs for easy
evaluation. The schematic of the BUF11702 demo
board is shown in Figure 53. Note that the demo board
has been configured for single-supply use. As such, all
decoupling capacitors are connected to the ground
plane of the demo board, as are the ground terminals of
the BUF11702.
In populated versions of the demo board, capacitors C
1
to C
4
have been included. Capacitors C
1
and C
2
are
bulk decoupling capacitors of 6.8µF, whereas
capacitors C
3
and C
4
are 100nF ceramic
high-frequency decoupling capacitors. Resistors R
1
to
R
32
and capacitors C
5
to C
16
have not been included
and are application-specific.
