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 DAC8581EVM as well as all necessary power for the DSP. Clean, well-regulated
analog power for the DAC8581EVM 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.
