________________General Description

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

loop buffers featuring high slew rate, high output cur-

rent, low noise, and excellent capacitive-load-driving

capability. The MAX4200/MAX4201/MAX4202 are sin-

gle buffers, while the MAX4203/MAX4204/MAX4205 are

dual buffers. The MAX4201/MAX4204 have integrated

50

Ω termination resistors, making them ideal for driv-

ing 50

Ω transmission lines. The MAX4202/MAX4205

include 75

Ω back-termination resistors for driv-

ing 75

Ω 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-communica-

tions applications.
