Learning Board ADAU1401/ADAU1701 DSPmini Learning Board Update to ADAU1401 Single Chip Audio System Replacement

Features: The ADAU1401 is a complete single-chip audio system with built-in 28/56-bit audio DSP, ADC, DAC and microcontroller-like control interface. Signal processing techniques including equalization, crossover, boost, multi-band dynamic processing, delay compensation, speaker compensation, and stereo for image widening can be used to compensate for the practical limitations of speakers, amplifiers, and listening environments, dramatically improving the sound quality experience. The ADAU1401 program can be loaded from the serial EEPROM through its self-booting mechanism at power-up or from an external microcontroller. When turned off, the current state of the parameter can be written back to the EEPROM from the ADAU1401 to be recalled the next for time the program is run. This edition is suitable for ADAU1401/1701/1702 learning and product use. The ADAU1401 is more stable than the ADAU1701 in the harsh working environment of -40°-105° (the ADAU1701 is generally 0-70°). The program can be used universally and other indicators are the same. It has self-starting after power-on and can be completely separated from the single-chip operation. Application: Multimedia speaker system MP3 player speaker Car audio host Mini stereo system Digital Television Studio monitoring system Speaker divider Instrument sound processor for Seat sound system (aircraft / for coach) Specification: Dimensions: 3.5x5cm/1.38x1.97inch Color: Green Package includes: 1 x ADAU1401/ADAU1701 DSPmini Learning Board (without retail package)
