MAX4213 Evaluation Kit
General Description
The MAX4213 evaluation kit (EV kit) simplifies evalua-
tion of the MAX4213 high-speed, single-supply amplifi-
er with Rail-to-Rail
®
outputs. The EV kit circuit demon-
strates the MAX4213 in the noninverting unity-gain con-
figuration, in either single or dual-supply mode.
This EV kit may also be used to evaluate the MAX4215
high-speed, rail-to-rail buffer. Contact Maxim to order a
free sample.

Note:
To evaluate the MAX4215, request a MAX4215ESA free
sample.
Quick Start
The MAX4213 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) For single-supply operation, connect a +5V power
supply to the pad marked VCC. Connect the power-
supply ground to the VEE and GND pads.
2) Verify that a shunt is across pins 1 and 2 of JU1.
3) Connect the output marked OUT to an oscilloscope
input.
4) Turn on the power supply. Apply a +0.5V to +2.75V
signal to the SMA connector marked IN.
5) Verify the output signal on the oscilloscope.
Note:
If you use a 50Ω terminated oscilloscope input,
the output amplitude observed will be half that of the
input, due to the voltage divider formed by the 49.9Ω
back-terminating resistor (R1) and the oscilloscope
input termination.

MAX4213 Evaluation Kit
Evaluates: MAX4213/MAX4215
_______________Detailed Description
Supply Voltage
The MAX4213 EV kit can be used in either single or
dual-supply mode. Negative power-supply filter capaci-
tors C1 and C3 can be eliminated in your final single-
supply design.
Enable Logic-Low Input Current
Under certain conditions, the logic-low input current
can increase. The MAX4213 EV kit provides a resistor
location (R3) to limit the logic-low input current. A 10kΩ
resistor value is recommended. R3 is normally shorted
by a PC board trace between its pads. Be sure to cut
this shorting trace before installing a resistor. Refer to
the
Enable Input and Disabled Output
section of the
MAX4212/MAX4213/MAX4216/MAX4218/MAX4220
data sheet for further details.
Enable Control
The MAX4213 provides an enable pin (EN) to enable or
disable the output. Table 1 lists the options available for
the enable/disable control jumper JU1. You can use an
external controller by removing the shunt on JU1 com-
pletely and connecting the external controller to the
pad labeled EN. EN is a TTL/CMOS logic-level input.
Layout Considerations
The MAX4213 EV kit layout has been optimized for
high-speed signals and low distortion, with careful
attention given to grounding, power-supply bypassing,
and signal-path layout. The small, surface-mount,
ceramic bypass capacitors C1 and C2 have been
placed as close to the MAX4213 supply pins as possi-
ble. The ground plane has been removed around and
under the MAX4213 to reduce stray capacitance.
Capacitance at the inverting input pin has been mini-
mized by reducing the length and width of the input
and feedback traces, and by using 0805-size surface-
mount feedback and gain-set resistors.
