GENERAL DESCRIPTION
This user guide explains the design, setup, and operation of the
EVA L-ADAU1452MINIZ evaluation board.
This evaluation board provides access to the digital serial audio
ports of the ADAU1452, as well as some of its general-purpose
I/Os. An analog I/O is provided by the included AD1938 codec.
The ADAU1452 core is controlled by Analog Devices, Inc.,
SigmaStudio™ software, which interfaces to the board via a USB
connection. The board is powered by a 6 V dc supply, which is
regulated to the voltages required on the board. The printed
circuit board (PCB) is a 4-layer design, with a single ground
plane and a single power plane on the inner layers. The board
contains connectors for external analog inputs and outputs and
optical S/PDIF interfaces. The master clock is provided by the
integrated oscillator circuit and the on-board 12.288 MHz
passive crystal.
For more information about the ADAU1452 device, see the
ADAU1452 data sheet, which should be used in conjunction
with this user guide.
