Description

The MAX4204 is ultra-high-speed, openloop 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 MAX4204 uses 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.
