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 C1
to C4 have been included. Capacitors C1 and C2 are
bulk decoupling capacitors of 6.8µF, whereas
capacitors C3 and C4 are 100nF ceramic
high-frequency decoupling capacitors. Resistors R1 to
R32 and capacitors C5 to C16 have not been included
and are application-specific.
