ADI ADAU1401 SigmaDSP单片音频子系统解决方案 - 音频/视频/显示 - 电子工程网

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 I2C/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-ADAU1401AEBZ can also be used for evaluation of the pin-compatible ADAU1701 and ADAU1702 SigmaDSP reg;s. 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.
