EVALUATION BOARD HARDWARE
POWER SUPPLIES
EVAL-AD7991/AD7995 is powered via the 5 V supply from the
USB connector, J1. The 5 V supply can be used to power the
AD7991/AD7995 directly through the EMC_FILTER. A
regulated voltage from the on-board ADP3303, high precision,
low power, 3.3 V output voltage regulator can also be used.
Table 1 shows the positions in which all the links are set when
the evaluation board is shipped.
