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 50Ω terminating
resistors are included for test equipment compatibility.
♦ 780MHz -3dB Bandwidth
♦ 280MHz 0.1dB Gain Flatness
♦ 2.1nV/ Hz Voltage Noise Density

♦ 0.8pA/ Hz Current Noise Density

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 termina-
tion resistor, and the MAX4202 has an internal 75Ω out-
put termination resistor, while the MAX4200 has no
inte rna l outp ut te rmina tion re s is tor (re fe r to the
MAX4200–MAX4205 data sheet for more information).
♦ 4200V/µs Slew Rate
♦ Excellent Capacitive-Load-Driving Capability
♦ Fully Assembled and Tested Surface-Mount

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

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 50Ω 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 50Ω back-termi-
nating resistor and the oscilloscope input termina-
tion impedance.)
