Procedure
The MAX98360 and AUDINT3 boards are fully assembled
and tested. Follow the steps below to set up the EV
system for device evaluation.
AUDINT3 Board Setup
1) Connect the MAX98360 DEV board (two-row J1
connector) to the AUDINT3 board (three-row J1
connector). The bottom row of both J1 connectors
should be lined up so the standoffs on the corners
of the AUDINT3 and DEV board are level.
2) With the audio source disabled, connect the USB
cable from your computer to the USB port (J2) on
the AUDINT3 board. The AUDINT3 board provides
the BCLK and LRCLK signals as well as the power
for V , sourcing 1.8V to the DEV board through
DDIO
the J1 connector.

3) The multi-color LED D1 blinks white. When the
computer registers the AUDINT3 as a USB device,
D1 changes to magenta and blinks slowly.
DEV Board Setup
1) With all supplies unpowered, connect the 2.5V to
5.5V power supply across the VIN and GND binding
posts.
2) Connect the micro speaker leads across the FOUTP
and FOUTN binding posts.
3) Place the shunt on jumper J5 across pins V
4) Set the switch SW1 to the on position.
Test
1) Enable the supply voltages across each of the
supply pins.
2) Open the Windows Sound dialog and select the
Playback tab. A Speakers item similar to
should be listed as an available playback device.
3) Verify that the Speakers item is set as the default
device. Once this is done, the AUDINT3 board
outputs PCM data to the DIN pin on the DEV board.
4) Adjust the audio source volume to a low level.
5) Enable the audio source and verify that audio is
heard through the connected speaker. Adjust the
audio source volume as needed.
6) Quick start of the evaluation software is complete.
