ZPAQI ADAU1401 DSPmini Learning Board for Single Chip Audio Systems

The ZPAQI ADAU1401 DSPmini is a learning and development board designed for single-chip audio systems. Firmware can be loaded automatically at power-up using the board’s self-start mechanism or supplied by an external microcontroller. When closed, the current parameter settings can be written back into the ADAU1401 so the next program run will recall them.

Hardware includes two ADCs and four units that deliver a 98.5dB input dynamic for the output. A digital input/output port allows seamless connection to other ADCs. Communication with the ADAU1401 is available via I2Cbus or a four wire port.
