Selection window appears, click on the MAX5258
radio button and then press the Next button. The
EV kit software main window appears, as shown in
Figure 1.
7) To measure the OUTA voltage, connect the first
DVM between H2-1 (OUTA) and H2-2 (GND).
8) To measure the OUTB voltage, connect the second
DVM between H2-3 (OUTB) and H2-4 (GND).
9) Verify that the voltage on both DVMs is approxi-
mately 0V.
10) Enter 0x3F into the D7 - D0 (Shift Register Data
Bits) edit box.
11) Press the Load All DACs button.
12) Verify that the voltage shown on both DVMs is
approximately 1V.
Detailed Description of Software
The main window of the evaluation software (shown in
Figure 1) displays the voltages and codes for all DAC
input and output registers. In addition, the main window
has two tabs. The Load DACs tab sheet controls all of
the DAC loading features of the MAX5258. The
