AD8139
Since this is a single-ended-to-differential application on a
single supply, the input common-mode voltage swing must be
checked. From Figure 62, β = 0.52, V
OCM
= 2.4 V, and V
ICM
is
1.1 V p-p swinging about ground. Using Equation 16,
V
ACM
is
calculated to be 0.53 V p-p swinging about a baseline of 1.25 V,
and the minimum negative excursion is approximately 1 V.

Exposed Paddle (EP)
The SOIC-8 and LFCSP packages have an exposed paddle on
the underside of its body. In order to achieve the specified
thermal resistance, it must have a good thermal connection to one
of the PCB planes. The exposed paddle must be soldered to a pad
on top of the board that is connected to an inner plane with several
thermal vias.
