Figure 7. A Typical Application Schematic
As for any low noise designs, particular care has to be
taken when tackling Printed Circuit Board (PCB) layout.
The figure below gives an example of a layout where stray
inductances/capacitances are minimized. This layout is the
basis for the MC33761 performance evaluation board. The
BNC connectors give the user an easy and quick evaluation
mean.
