EVALUATION BOARD OVERVIEW
This data sheet describes the design and setup of the
EVAL-ADAU1701MINIZ, the ADAU1701 SigmaDSP® mini
evaluation board. The EVAL-ADAU1701MINIBZ provides
stereo line-level analog audio input as well as a digital audio
interface. Two of the ADAU1701 DAC channels are routed
to an SSM2306 filterless Class-D amplifier, while the other
two channels are routed to line-level outputs.
The ADAU1701 can be controlled via the USBi interface control
board connected to the I
2
C communications interface. On-board
self-boot EEPROM is included for operating the board inde-
pendently of the Analog Devices, Inc., SigmaStudio™ software.
Push-buttons, LEDs, and a potentiometer are connected
directly to the ADAU1701 GPIO pins for user control.
This evaluation board can also be used to evaluate the Analog
Devices ADAU1702 and ADAU1401 audio processors. Visit
www.analog.com for details about the differences between these
integrated circuits.
