POWERING UP THE EVALUATION BOARD
Power is supplied to the evaluation board using a dc power
supply with a female positive center plug. The plug has a 2.1 mm
inner diameter, a 5.5 mm outer diameter, and a 9.5 mm length
(see
Figure 4). The output must range between 4.5 V and 7 V and
must be able to source at least 1.5 A of current. Connect the power
supply to Connector J4. The unregulated supply powers the
operational amplifiers used in the active audio filters for the
analog audio inputs and outputs. An on-board linear regulator
(U17) generates the 3.3 V dc supply required for the
ADAU1467
and AD1937 , as well as other supporting ICs. When the power
supply is connected properly, LED D9 illuminates.
Figure 4. DC Power Supply Plug and Cable
To power up the evaluation board, take the following steps:
1.
Connect the included power supply to the wall outlet
(100 V to 240 V, ac 50 Hz to 60 Hz).
2. Connect the female plug of the power supply to the J4 male
connector on the EVAL-ADAU1467Z, as shown in Figure 5.
3. After the power supply is connected, the D9 status LED
(A_3V3) illuminates.

CONNECTING THE USBI
Connect the ribbon cable of the USBi to the control port of the
EVAL-ADAU1467Z (see Figure 6). The USBi must already be
connected to the USB 2.0 port of the computer. When the USBi
is connected properly, LED D8 illuminates.
