The exposed-pad, 20-pin, TQFN package incorporates
features that provide a very low thermal-resistance path
for heat removal from the IC. The exposed pad on the
MAX4951 must be soldered to GND for proper thermal
and electrical performance. For more information on
exposed-pad packages, refer to Maxim Application
Note HFAN-08.1: Thermal Considerations of QFN and
Other Exposed-Paddle Packages .
Use controlled-impedance transmission lines to inter-
face with the MAX4951 high-speed inputs and outputs.

As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against electro-
static discharges encountered during handling and
assembly. The MAX4951 is protected against ESD up
to ±5.5kV (Human Body Model) without damage. The
ESD structures withstand ±5.5kV in all states: normal
operation and powered down. After an ESD event, the
MAX4951 continues to function without latchup.
