Adopt CS493264 audio DSP, CS8415 96KHz digital receiver, 96 KHz/24bit ADC and DAC.
Support Dolby digital, Dolby PRO-logic, and DTS and so on, with many kinds of listening modes and sound field effect playbacks.
Analog audio frequency output, can select low-pass filter circuits by itself so as to realize different effects.
Full-range bandwidth (20Hz to 20K Hz), user can adjust bandwidth through low-pass filter.

Digital and analog ground wires are independent, which lowers the requirement of motherboard PCB LAYOUT and gets better performance.
Use I2C slave interface to connect user mainframe, and it is okay to use existing I2C interface without adding additional interface
I2C interface can be used with another I2C device in parallel. DA32UD is the same as many I2C devices such as 24C01 and so on, and it's easy for users to do secondary development.

Built-in memory space with 30 bytes, its function is the same as 24C01, and there is no need for users to use memory chips such as 24C01, 93C46 and so on any more.
Several universal I/O ports, it is okay to can use built-in CPU to complete whole machine functions.
Directly mounted on the board as an integrated product with audio board, which improves the traditional connection of decoder and enhances the reliability and appearance of product.
