APPLICATION INFORMATION
BUF11702 evaluation module (SLOP356)
The BUF11702 has an evaluation module where it 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 EVM is shown below. Note that the EVM has been configured for
single supply use. As such, all decoupling capacitors are connected to the ground plane of the EVM, as are the
ground terminals of the BUF11702.
