ADAU1701 DSP Easy Start Board (P2P ADAU1401)

Description

ADAU1701/1401 is a complete single-chip audio system with built-in control interfaces for 28 / 56-bit audio DSP, ADC, DAC, and similar microcontrollers. Signal processing technologies including equalization, crossover, bass enhancement, multi-band dynamic processing, delay compensation, speaker compensation, and stereo image widening can be used to make up for the practical limitations of speakers, amplifiers, and listening environments, thereby significantly improving the sound quality experience.

This signal processing technology is comparable to that used in high-end studio equipment. Most processing is done in full 56-bit double-precision mode, resulting in excellent low-level signal performance. The ADAU1401 is a fully programmable DSP. With the easy-to-use SigmaStudio software, users can configure modules for custom signal processing in a graphical manner using modules such as biquad filters, dynamic processors, level control, and GPIO interface control.

The ADAU1401 program can be loaded from serial EEPROM through its self-booting mechanism at power-up or from an external microcontroller. When shutting down, the current state of the parameters can be written back to the EEPROM from the ADAU1401 so that it can be recalled the next time the program is run.

Two ADCs and four DACs provide 98.5 dB of analog input to analog output dynamic range. Digital input and output ports allow seamless connection with other ADCs and DACs. The ADAU1401 communicates via an I2C bus or a four-wire SPI port.

This version is suitable for ADAU1401 / 1701/1702 learning and product use. Compared with ADAU1701, ADAU1401 is more stable in the harsh working environment of -40 ° -105 ° ADAU1701 is generally 0-70 °. The procedures can be used universally. . With power-on self-starting, it can run completely independently of the microcontroller. All function ports are derived, which can expand digital I2S input / output / key function / LED drive / auxiliary ADC potentiometer analog / encoder volume adjustment.

The 4-bit SWITCH can enable you to turn on/off EEPROM's write protect, PLL setting etc. and we can also support external MCLK input if needed.

Provide schematic diagrams and many usage routines. A typical input-output with EQ demonstration program is burn by default and can be replaced with your own function at any time.

We also provide the audio board for MW-1701/1401MINI core board, please select the 3rd kit with EXT board if you need.

Which enable you connect plug USBi emulator and analog/IIS input/output more easily, you can also power the board through pin or USBi.

Thanks!
