• [ADAU1451] The PNP transistor drive by VDRIVE pin for ADAU1451 DVDD

    Dear Sir,

    Our customer met an issue, their product(speaker) using ADAU1451 had finished development stage and MP for a while, but their end customer returned the failures set to them (2 sets in this Feb, 3 sets in May of end, total 5 failures sets) from…

  • [ADAU1451] I2S microphone configuration with AEC algorithm

    Hello all,

    I am not experienced in audio signal processing and I have never worked with SigamaStudio or any Analog Devices' DSP, therefore I am having some difficulties.

  • Demux ADAU1451

    We are designing a digital audio console with ADAU1451 DSP

    We need to use the Aout3 TDM 8 output  of ADAU 1451  to get four AES-3 outs. How can we demux the 8 channels to use four  DIT 4096 Texas stereo serial audio to AES converters?  
    Or do you know another…

  • ADAU1451 output port

    Dear sir,

    Our customer's project have four serial out from ADAU1451. OUT3 have independent BCLK/LRCK;

    for layout board size and EMC concern, OUT1 and OUT2 share BCLK0/LRCK0 from OUT0 (PORT1 and PORT2 BCLK/LRCLK no layout, pin in open state).

  • ADAU1451 hardware accelerator Slew

    Hi，

    HenryLj.mo

    请问下在Sigma 300里面使用硬件加速器slew，slew mode为RC type时，对应的time constant 与数据从当前值到目标值得时间有什么关系,或者说不同的time constant的值有什么用？

    Thanks,
