3.3 MAXREFDES5 4-Ch AFE Board

Connect the MAXREFDES5 board to the USB2PMB1 adaptor. Both connectors should be on the same side of
the PCB when mated together as shown below.

3.3.1 Analog Signal Connections

The following table summarizes the different connection options for the MAXSANTAFEEVSYS kit. Note the
input range of the MAXREFDES5 analog inputs exceeds the output capabilities of the MAX5216DACLITE
board included with the kit.

For testing input AIN2 with a voltage source, a jumper JU2 should be removed to disconnect the on-board
sense resistor. Jumper JU1 on AIN2 is provided for optional connection to a reference ammeter.
