APPLICATIONS INFORMATION
on the digital inputs is imperceptible, thanks to the digital
input hysteresis)
Just by maintaining separate areas on the GND plane
where analog and digital return currents naturally fl ow,
good results are generally achieved. Only after this has
been done, it is sometimes useful to interrupt the ground
plane with strategically placed “slots”, to prevent the digital
ground currents from fringing into the analog portion of
the plane. When doing this, the gap in the plane should be
only as long as it needs to be to serve its purpose.

Caution: if a GND plane gap is improperly placed, so that
it interrupts a signifi cant GND return path, or if a signal
traces crosses over the gap, then adding the gap may
greatly degrade performance! In this case, the GND and
signal return currents are forced to fl ow the long way
around the gap, and then are typically channeled directly
into the most sensitive area of the analog GND plane.
