MAX14483 Evaluation Kit Evaluates: MAX14483 General Description Features The MAX14483 evaluation kit (EV kit) provides a proven Six Unidirectional Channels with Different Channel design to evaluate the MAX14483, 6-channel, 3.75kV , Direction Configuration and Data Speed (Up to RMS SPI digital isolator. The EV kit allows easy access to all six 200Mbps) channels through either SMA connectors or test points. On-Board LEDs Indication of Device Ready for On-board LEDs on the ready signals (SAA and SBA) and Communication FAULT output directly indicate the signals status. SMA Connectors for Easy Connection to External The EV kit should be powered from two independent Equipment isolated power supplies with nominal output voltage in Wide Power Supply Voltage Range from 1.71V to 5.5V range from 1.71V to 5.5V. For evaluating the electrical parameters of the device without any isolation between Guaranteed Up to 3.75kV Isolation for the 20-pin RMS SSOP Package for 60s the two sides, a single power supply can also be used. -40C to +125C Temperature Range The MAX14483EVKIT comes populated with the MAX14483AAP+ installed in a 20-pin SSOP package Proven PCB Layout with 5.5mm of creepage and clearance. Fully Assembled and Tested Ordering Information appears at end of data sheet.

Two DC power supplies with output range of 1.71V 3) Set both DC power supply outputs between 1.71V to 5.5V and 5.5V, and then enable the power supply outputs. Note: It is also possible to power the EV kit from a Signal/function generator single power supply to test electrical parameters but Oscilloscope this invalidates the digital isolation of the IC. Procedure 4) Verify that yellow LEDs SAA and SBA are both on, The MAX14483 EV kit is fully assembled and ready for indicating side A and side B are operating normally. evaluation. For manual verification follow the steps below 5) Connect the signal/function generator to ISDO SMA to verify board functionality: connector or HEADER1 Pin 4 and observe the isolat- ed signal on the OSDO SMA connector or HEADER2 1) Verify jumper settings. See Table 1 for all shunt positions. Pin 4 using an oscilloscope. J1 and J2 are closed.
