GENERAL DESCRIPTION
This user guide details the design and setup of the EVAL-
ADAU1861EBZ evaluation board. The EVAL-ADAU1861EBZ pro-
vides all the analog and digital inputs and outputs on the
ADAU1861. The ADAU1861 core is controlled by Analog Devices,
Inc., Lark Studio graphical user interface (GUI) software, which
interfaces with the EVAL-ADAU1861EBZ by a USB connection.

User Guide | EVAL-ADAU1861
The EVAL-ADAU1861EBZ can be powered by the USB bus or by
a single 12 V supply. Any of these supplies are regulated to the
voltages required on the EVAL-ADAU1861EBZ.
The printed circuit board (PCB) of the EVAL-ADAU1861EBZ is a
4-layer design, with a ground plane and a power plane on the inner
layers. The EVAL-ADAU1861EBZ contains connectors for external
microphones and speakers. The main clock of ADAU1861 can be
provided externally or by the on-board 24.576 MHz oscillator or
crystal.
The EVAL-ADAU1861EBZ contains a microphone array, aim for
beamforming. A 16-channel, high performance, 192 kHz, 24-bit
digital-to-analog converter (DAC) is used as the analog output for
audio tuning. For compatibility with 3.3 V inputs and outputs, all
digital audio interfaces can be transferred to 3.3 V inputs and
outputs from 1.8 V with a level shifter.
For full details on the ADAU1861, see the ADAU1861 data sheet,
which must be consulted with this user guide when using the
EVAL-ADAU1861EBZ evaluation board.
