OPTIONS

The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation board

can be powered using the on-board ADP5071 or from well regu-

lated bench supplies. See Table 1 for the on-board jumper configu-

rations for each power supply solution.

The on-board ADP5071, supplied with a 3.3 V supply via the

PWR_SEL connector, or the supply from the SDP-K1 (in this

configuration, make sure to supply AVCC externally; AVCC_SEL:

2-3), can power the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ eval-

uation boards. Alternatively, the evaluation boards can also be

powered externally; AVDD and AVSS through the P8 connector while

AVCC uses the EXT_AVCC connector. See Figure 3 for a function-

al block diagram of the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ

evaluation boards.

For either power supply option, place the links in their required

operating set up before supplying the evaluation boards (see Table

3).
