General Description

The MAX4200–MAX4205 are ultra-high-speed, open-

loop buffers featuring high slew rate, high output current,

low noise, and excellent capacitive-load-driving capability.

The MAX4200/MAX4201/MAX4202 are single buffers,

while the MAX4203/MAX4204/MAX4205 are dual buffers.

The MAX4201/MAX4204 have integrated 50Ω termination

resistors, making them ideal for driving 50Ω transmission

lines. The MAX4202/MAX4205 include 75Ω back-

termination resistors for driving 75Ω transmission lines.

The MAX4200/MAX4203 have no internal termination

resistors.

The MAX4200–MAX4205 use a proprietary architecture

to achieve up to 780MHz -3dB bandwidth, 280MHz 0.1dB

gain flatness, 4200V/μs slew rate, and ±90mA output current

drive capability. They operate from ±5V supplies and draw

only 2.2mA of quiescent current. These features, along

with low-noise performance, make these buffers suitable

for driving high-speed analog-to-digital converter (ADC)

inputs or for data-communications applications.
