Operating Basics
Parasitic capa
citance between analog and digital reference. Parasitic capacitance
can occur between the input references mutually. For example, between an analog
and digital reference. For this reason, you should connect the references to a
system ground or another stable voltage. If the reference of an input is connected
to a high speed and/or high voltage signal, you should be aware of parasitic
capacitance. (See Figure 10.)

This is the correct way to connect reference leads. (See Figure 11.)
