Exposed-Pad Package

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.

Layout

Use controlled-impedance transmission lines to inter-

face with the MAX4951 high-speed inputs and outputs.

Place power-supply decoupling capacitors as close as

possible to VCC.

ESD Protection

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.
