Ultra-High-Speed, Low-Noise, Low-Power,
SOT23 Open-Loop Buffers
________________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
50Ω termination resistors, making them ideal for driv-
ing 50Ω transmission lines. The MAX4202/MAX4205
include 75Ω back-termination resistors for driv-
ing 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-communica-
tions applications.
