PCB layout example
Figure 21 shows a PCB layout example for the application schematic in Figure 20.
A double-sided FR-4 board of 1.6mm thickness is used. This PCB has a ground plane
on the bottom layer. Additionally, there are ground areas on the component side of the
board to ensure sufficient grounding of critical components. A large number of via
holes connect the top layer ground areas to the bottom layer ground plane.
