CAUTION
DO NOT connect the MMB0 to your PC before installing the DXP software as
described in the DXP User’s Guide. Installing the software first ensures that the
necessary drivers are properly loaded to run the hardware.

MMB0 Power Supplies
Several power connections are required for the hardware to work properly. For the MMB0, the supplied
6-V ac/dc converter is all that is necessary. Be sure that J12 on the MMB0 board is closed before
connecting the ac/dc adapter to the DC In connector of the MMB0. This supply provides all power to the
digital portion of the DAC8832EVM as well as all necessary power for the DSP. Clean, well-regulated
analog power for the DAC8832EVM should be supplied externally via J14, a six-position screw terminal
mounted in the lower left corner of the MMB0 board.

CAUTION
When using external power supplies applied to J14 on the MMB0, please
ensure all shorting blocks from J13 are completely removed. Permanent
damage to the MMB0 may occur otherwise.

From left to right, the J14 screw terminal connections are –VA, +VA, +5VA, –5VA, +5VD, and GND. The
5V from the ac/dc adapter can be connected to the +VA or the +5VA by installing a jumper across JP13A
or JP13B. If the jumpers are not installed, the analog V
