EVALUATION BOARD HARDWARE
INITIAL SETUP CONDITIONS
Care should be taken before applying power and signals to the
evaluation board to ensure that all link positions are set as
required by the operating mode.
POWER SUPPLIES
The EVAL-AD7997EBZ/AD7998EBZ are powered via the 5 V
supply from the USB connector, J1. The 5 V supply can be used
to power the
A regulated voltage from the on-board ADP3303, a high pre-
cision, low power, 3.3 V output voltage regulator, can also be
used. To select the power supply for the AD7997/AD7998, choose
LK7 (see the Links section).
USB CONNECTOR
A standard USB connector, J1, is used to connect the evaluation
board to the USB port of a PC. A standard USB connector cable
is included with the AD7997/AD7998 evaluation board kits.

Because the USB connector powers the board, there is no need
for an external power supply.
Communication between the AD7997/AD7998 evaluation
boards and the PC is over the USB interface. The on-board USB
controller controls this communication.
SOCKETS
There are 10 input sockets (AN0 through AN7, J2, and J3)
relevant to the operation of the AD7997/AD7998 on these
evaluation boards. The functions of these sockets are outlined
in Table 1.
