Exposed Paddle (EP)
Because this is a single-ended-to-differential application on a
single supply, the input common-mode voltage swing must be
1.1 V p-p swinging about ground. Using Equation 16, VACM 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.
The 8-lead SOIC and the 8-lead LFCSP have an exposed paddle
on the bottom of the package. To achieve the specified thermal
resistance, the exposed paddle must be soldered to one of the
PCB planes. The exposed paddle mounting pad should contain
several thermal vias within it to ensure a low thermal path to
the plane.
