ADAU1401A, ADAU1401, ADAU1701, and ADAU1702 SigmaDSP Evaluation Board

GENERAL DESCRIPTION

The EVAL-ADAU1401AEBZ is a platform that operates all of
the ADAU1401A's functions with a full range of analog and
digital inputs and outputs. Digital I/O connections are available
in both S/PDIF and 3-wire serial data formats. The DSP is
controlled by the SigmaStudio™ software, which interfaces to
the board through a USB connection. This evaluation board is
powered by a single supply, which is regulated to the proper
voltages on the board. The PCB is in a 6" × 6" 4-layer design,
with a single ground plane and a single power plane on the
inner layers.
The ADAU1401A can be controlled via the USBi interface
control board connected to the I
interface. On-board self-boot EEPROM is included for
operating the board independently of the SigmaStudio software.
Push-buttons, LEDs, potentiometers, and other interface
options on the included GPIO board can be connected to the
evaluation board to enable GPIO control.
The EVAL-ADAU1401AEBZ can also be used for evaluation of
the pin-compatible
The differences between the ADAU1401A, ADAU1401,
ADAU1701, and ADAU1702 are:
•
The ADAU1701, ADAU1401A, and ADAU1401 have 1024
program RAM locations, while the ADAU1702 has 512
program RAM locations.
•
The ADAU1701 has 2k words of data memory, while the
ADAU1702 has 0.5k words of data memory.
