The MAX4754A EV kit board provides a One +5V DC power supply proven layout for evaluating the MAX4754A. The EV kit One ohmmeter comes with a MAX4754AETE+ installed. Procedure Switch Control The MAX4754A EV kit is fully assembled and tested. There are two jumpers (JU1 and JU2) on the MAX4754A Follow the steps below to verify board operation. EV kit board, which individually control the logic level of Caution: Do not turn on the power supply until all the digital control inputs INA and INB, as shown in connections are completed. Tables 1 and 2. Refer to the MAX4754A data sheet for a detailed description of the switching function. 1) Turn off the 5V DC power supply. 2) Make sure the shunts of all jumpers are in the follow- Power Supply ing default positions: The MAX4754A EV kit is powered from a user-supplied +1.8V to +5.5V DC power supply connected to the JU1: (1-2) INA is high VDD and GND pads. 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 Table 2.
