MAX4754A Evaluation Kit
Quick Start
Recommended Equipment
? One +5V DC power supply
? One ohmmeter
Procedure
The MAX4754A EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Turn off the 5V DC power supply.
2) Make sure the shunts of all jumpers are in the follow-
ing default positions:
JU1: (1-2) INA is high
JU2: (1-2) INB is high
3) Connect the (-) terminal of the 5V DC power supply
to any GND pad of the MAX4754A EV kit. Connect
the (+) terminal to the VDD pad.
4) Connect one terminal of the ohmmeter to the COM1
pad of the MAX4754A EV kit. Connect the other ter-
minal of the ohmmeter to the NC1 pad.
5) Turn on the 5V DC power supply.
6) Remove the shunt of jumper JU1, then put it back
on; observe the display difference of the ohmmeter
during the jumper changing

Detailed Description of Hardware
The MAX4754A is a 0.5 Ω , quad SPDT switch with dual
control lines. The MAX4754A EV kit board provides a
proven layout for evaluating the MAX4754A. The EV kit
comes with a MAX4754AETE+ installed.
Switch Control
There are two jumpers (JU1 and JU2) on the MAX4754A
EV kit board, which individually control the logic level of
the digital control inputs INA and INB, as shown in
Tables 1 and 2. Refer to the MAX4754A data sheet for a
detailed description of the switching function.
Power Supply
The MAX4754A EV kit is powered from a user-supplied
+1.8V to +5.5V DC power supply connected to the
VDD and GND pads.
