________________General Description

The MAX4201 evaluation kit (EV kit) simplifies evalua-

tion 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 configura-

tion. RF-style connectors (SMA) and 50

Ω 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 50

Ω output termina-

tion resistor, and the MAX4202 has an internal 75

Ω out-

put termination resistor, while the MAX4200 has no

internal output termination resistor (refer to the

MAX4200–MAX4205 data sheet for more information).

_________________________Quick Start

The MAX4201 EV kit is fully assembled and tested.

Follow these steps to verify board operation. Do not

turn on the power supply until all connections are

completed.

1) The circuit requires supply voltages of ±4.0V to

±5.5V. For evaluation purposes, connect a +5V

supply to the pad labeled VCC and a -5V supply to

the pad labeled VEE. Connect the power-supply

grounds to the pad marked GND.

2) Connect the output marked OUT to an oscilloscope

through a terminated 50

Ω cable.

3) Turn on the power supply. Apply a signal of ±3.3V

maximum to the SMA connector marked IN+.

4) Verify the output signal on the oscilloscope. (Note:

When using a 50

Ω terminated oscilloscope input,

the output amplitude observed on the oscilloscope

will be half that on the input. This is due to the volt-

age divider formed by the internal 50

Ω back-termi-

nating resistor and the oscilloscope input termina-

tion impedance.)
