Two and four provide 98.5 of analog input to analog output dynamic . Seamless connection to other and is possible with digital input and output ports. The ADAU1401 communicates over or a four-wire SPI port.

The ADAU1401 program can be loaded from the through its self-booting mechanism at or from external microcontroller. When turned off, the current of the parameter can be written back to the from the ADAU1401 to be recalled the next 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.

The ADAU1401 is a single-chip with built-in 28/56-bit , , and microcontroller-like control . processing techniques including equalization, , bass , multi-band dynamic processing, delay compensation, compensation, and stereo image widening can be used to for the practical limitations of speakers, amplifiers, and listening environments, dramatically improving the sound experience.

It has self-starting after power-on and can be completely separated from the single-chip . Leads to all function ports, which can expand digital I2S input/output/key function/LED /auxiliary (potentiometer analog)/ adjustment.
