Ultra-High-Speed, Low-Noise, Low-Power, SOT23 Open-Loop Buffers

Product Details

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.

Description

The MAX4201 evaluation kit (EV kit) simplifies evaluation of the MAX4201 ultra-high-speed, low-power, low-noise, open-loop buffer. The EV kit circuit demonstrates the MAX4201 in the noninverting unity-gain configuration. RF-style connectors (SMA) and 50Ω terminating resistors are included for test equipment compatibility.

This EV kit can also be used to evaluate the MAX4200 and MAX4202 (contact Maxim for free samples). Note that the MAX4201 has an internal 50Ω output termination resistor, and the MAX4202 has an internal 75Ω output termination resistor, while the MAX4200 has no internal output termination resistor (refer to the MAX4200–MAX4205 data sheet for more information).
