MAX5581 EV System

The MAX5581 EV system is a complete, 4-channel, 12-

bit, data-generation system consisting of a MAX5581

EV kit and the Maxim CMODUSB command module.

CMODUSB Command Module

The CMODUSB uses a proprietary design to provide

ous Maxim devices. Maxim reserves the right to

change the implementation of this module at any time

with no advance notice.

CMODUSB Power Supply

The CMODUSB board uses a MAX1658 linear voltage

regulator. Jumper J1 selects between a 5V or 3.3V sys-

tem supply voltage. Do not plug a wall cube into the

P1 power jack since power is provided from the

USB port.

The Read UPIO Inputs tab, shown in Figure 9, allows

the user to read the GPI status for UPIO2. Pressing the

Read button not only tells the user whether a falling

edge or rising edge has occurred since the last read,

but also the current state of the pin.

Note: This read requires that UPIO1 be configured for

DOUTRB and UPIO2 be configured as a GPI.
