The ADP1053 daughter card PCB is 28 mm × 50 mm. A
40-pin connector is soldered to the back of the daughter
card evaluation board (see Figure 2).
Figure 2. Backside of the Daughter Card
The 40-pin connector plugs directly into an existing
evaluation motherboard. A 5 V source from the USB connection
provides power to the on-board
provides the 3.3 V power to the ADP1053.
Figure 3 shows the pin assignments for the 40-pin connector on
the ADP1053 daughter card evaluation board.
