• RE: DM0 and DM1 after reset in ADAU1450

    I haven't used SigmaStudio in a while, so I can't tell you what those compiler options do. My suggestion would be to just test them.

    Should it be needed, here's a variant of my program that also clears PM (except for the program itself obviously…

  • RE: Are writes with IPAT in ADAU1450 done at the end of a sample?

    Hello Reini,

    The IPAT table writes are exactly the same as safeload writes. They are done at the end of the regular code before the end of the frame. 

    I do want to add that in this processor you can write the gains without safeload or the IPAT table without…

    Just found this post after several days of searching. Had been pulling my hair out over this...

    Seeing the exact bug described on a board I designed. I am using port 0 as output, with LRCLK and BCLK both as master. I set port1 to slave from clk domain…

  • ADAU1450 multipurpose ports MP0/1/2/3/6/7 LED drive?

    Hello all,

    The datasheet of the ADAU1450 states that digital output ports cannot be used to drive a LED (page 8: $Electrical Characteristics, Digital Input/Output). Nothing is said explicit about the multipurpose pins. Does anyone know if the outputs…

  • Popping Noises with the ADAU1450

    In my project I used the ADAU1450 to self-boot. I‘m having trouble with popping noise when I switched EQ.

    I have used DC-BLOCKING in my design. I also tried to mute before switching data, but these effects are not ideal.

    I would be very grateful…

  • ADAU1450 通过AUX ADC 检测电压值,如何使用 ReadBack 模块读取,他们的对应关系是怎样的


                  ADAU1450  通过AUX ADC 检测电压值,如何使用 ReadBack 模块读取,他们的对应关系是怎样的。

    比如,AUX ADC 脚1Vdc,对应的ReadBack  (8.24 格式或32.0格式)是多少?
