Refer to
Figure 1
for locations of test points and
major components. The board comes configured
for “plug-and-play” WaveVision evaluation.
1. Run the WaveVision 4 program, version 4.4 or
higher is required to interface to the WV4
board. While the program is loading, continue
below.
2. Connect a USB cable between the WV4 board
and the PC running the WaveVision 4
software.
3.
Make the following required jumper
connections, see
Table 1
for more details:
•
JP9
- pins 1 & 2
•
JP7
- pins 2 & 3
•
JP6
- pins 1 & 2
•
JP8
- pins 1 & 2
•
JP10
- pins 1 & 2
4. Connect the
J1
header on the
DAC121C08XEB evaluation board to the WV4
serial connector (
J7
) on the WV4 board.
Refer to
Figure 3
for the serial connection and
Figure 4
for the J1 header pin out.
Note
: J1 on the DAC121C08XEB is
intentionally stuffed on the bottom side of the
board.

5. Perform step 7 of section 3.1 to configure the
loading of the analog output (V
OUT
).
6. Perform step 8 of section 3.1 to configure the
I
2
C slave address of the DAC.
7. Connect a clean (not switching) +5.0V power
source with a 350mA current limit to power
connector
J1
on the WV4 board. Turn on the
