General Description

The MAX5258 evaluation kit (EV kit) provides a proven

design to evaluate the MAX5258 low-power, 8-bit octal,

digital-to-analog converter (DAC). The EV kit also

includes Windows

2000/XP- and Windows Vista

-com-

patible software that provides a simple graphical user

interface (GUI) for exercising the features of the

MAX5258.

The MAX5258 EV kit PCB comes with a MAX5258EEE+

installed. This EV kit can also be used to evaluate the

MAX5259EEE+ low-power 8-bit octal DAC (2.7V to 3.6V).

Contact the factory for free samples of the

MAX5259EEE+.

The Load Setting(s) buttons must be pressed to write the corresponding mode settings to the DAC(s). Software Reset Press the Reset All Registers button to reset the MAX5258’s registers and GUI to the power-on-reset (POR) state. This can be done at any time and is highly recommended after using the Advanced User Interface window (Figure 3). Figure 2.

MAX5258 Evaluation Kit Detailed Description of Hardware The MAX5258 EV kit provides a proven layout for the MAX5258. An on-board analog output signal header (H2), an on-board digital input/output signal header (H3), and jumpers to disconnect the on-board microcontroller are all included on the EV kit. Figure 3.
