GENERAL DESCRIPTION
This user guide explains the design and setup of the EVAL-
ADAU1772Z evaluation board.
This evaluation board provides full access to all analog and digital
I/Os on the ADAU1772. The ADAU1772 core is controlled by
Analog Devices, Inc., SigmaStudio™ software, which interfaces to
the board via a USB connection. The EVAL -ADAU1772Z can be
powered by a single AAA battery, by the USB bus, or by a single
3.8 V to 6 V supply; any of these are 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 micro-
phones and speakers. The master clock can be provided externally
or by the on-board 12.288 MHz passive crystal.
