MAX4188 Evaluation Kit
General Description
The MAX4188 evaluation kit (EV kit) simplifies evalua-
tion of the MAX4188 triple, low-power, current-feedback
amplifier. The MAX4188 amplifier is set to a gain of
+2V/V. SMA connectors and 50鈩?terminating resistors
are included for 50鈩?test equipment compatibility. For
video test equipment compatibility, simply change the
terminating resistors to 75鈩?and change R
F
and R
G
resistors to the values shown in the MAX4188/
MAX4189/MAX4190 data sheet.
The EV kit comes with the MAX4188 installed. To evaluate
the MAX4189, order a free sample (MAX4189ESD),
replace the MAX4188 with the MAX4189 on the EV board,
and change the gain-setting and feedback resistors for
unity gain as shown in the MAX4188/MAX4189/
MAX4190 data sheet.

The MAX4188 EV kit is fully assembled and tested.
Follow these steps to verify board operation.
1) The circuit requires supply voltages of 鹵2.25V to
鹵5.5V. For evaluation purposes, connect a +5V sup-
ply to the pad labeled VCC and a -5V supply to the
pad labeled VEE. Connect power-supply ground to
the pad labeled GND.
2) Connect an output (OUT1鈥揙UT3) to an oscilloscope
input. Remove shunt from the corresponding jumper
(JU1鈥揓U3) to enable the selected amplifier.
3) Turn on the power supply. Apply a 鹵1.35V signal to
the appropriate amplifier input (IN1鈥揑N3). The 100鈩?/div>
load (chosen for ease of evaluation) limits the output
voltage range. Wider output voltage swings are
achievable with lighter loads. See the MAX4188/
MAX4189/MAX4190 data sheet.
4) Verify the output signal on the oscilloscope.
