GENERAL DESCRIPTION
The EVAL-ADAU1401EBZ is a platform that operates all of the
ADAU1401'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 ADAU1401 can be controlled via the USBi interface control
2
board connected to the I
C/SPI communications 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-ADAU1401EBZ can also be used for evaluation of
the pin-compatible
ADAU1701
The differences between the ADAU1401, ADAU1701, and
ADAU1702 are:
•
The ADAU1701 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.
