Applications Information
Layout
Circuit board layout and design can significantly affect
the performance of the MAX4986. Use good, high-fre-
quency design techniques, including minimizing ground
inductance and using controlled impedance transmis-
sion lines on data signals. It is recommended to place
1FF and 0.01FF power-supply bypass capacitors in
parallel as close to VCC as possible for each VCC pin.
Always connect VCC to a power plane.
Exposed-Pad Package
The exposed-pad, 42-pin TQFN package incorporates
features that provide a very low-thermal resistance
path for heat removal from the IC. The exposed pad
on the MAX4986 must be soldered to the circuit board
ground plane for proper thermal performance. For
more information on exposed-pad packages, refer
to Maxim Application Note 862: HFAN-08.1: Thermal
Considerations of QFN and Other Exposed-Paddle
Packages.
