Proper voltage-supply bypassing is essential for high-
frequency circuit stability. Bypass each V
TAPMAIN/TAPDIV with the capacitors shown in the
Typical Application Circuit (see Table 2 for component
values). Place the TAPMAIN/TAPDIV bypass capacitors
to ground within 100 mils of the pin.

The exposed pad (EP) of the MAX19985A’s 36-pin thin
QFN-EP package provides a low thermal-resistance
path to the die. It is important that the PCB on which the
MAX19985A is mounted be designed to conduct heat
from the EP. In addition, provide the EP with a low-
inductance path to electrical ground. The EP MUST be
soldered to a ground plane on the PCB, either directly
or through an array of plated via holes.
