• Configuring the AD2428

    Hello all,

    our host processor has a connection with AD2428 and I need to configure the AD2428 for my automotive application.

    I cannot use the sigma studio because we don't have the external usb connection from the board and our processor is not listed…

  • A2B AD2428 TDM issue

    1. We use AD2428 TDM format: TDM16, 48K, 32bit, TX0&TX1, RX0&RX1, TX1 for audio recoreding, BCLK=24.576Mhz.  Our TDM PCB routing length is about 200mm.  BCLK and SYNC as a PCB routing group. TXn as a PCB routing group. RXn as a PCB routing group…

  • EVAL-AD2428WD1BZ Routing Audio from AD2428 -> HP outputs


    First of all, this is the first time I'm using SigmaStudio so I know I have a lot to learn but I'm having some issues.

    I'm using the EVAL-AD2428WD1BZ with a slave microphone AD2428. I want to run the audio straight from the AD2428 to…

  • Data distortion STM324l micro is host to A2B bus (AD2428)


    I am currently using a STM32L4 micro as a host to the AD2428 master transceiver with one AD2428 slave node. I made use of Sigma studio to generate the bus configuration C file (attached) and make use of the SAI on the STM micro to acquire data…

  • A2B compatibility (AD2428-Master / AD2433-Slave)

    Hi Sir,

    We had AD2428 in production, it works when master and slave are in AD2428.

    When I try to use AD2433 for slave, I got timeout when in simple discovery.

    Is it compatible with our case? or any code need change?

    Thanks and best  regards,


  • AD2428 - A2B discovery mechanism


    I am using AD2428 Analog device , in that i am trying to make discovery for a2b node.

    Now the question is, do we really need to make i2s/DMA is up or only I2C communication is enough to do a simple discovery?

    Do i need to connect the…

  • Purpose of ACM/BCM pins on AD2428?

    The datasheet for the AD2428 mentions that the ACM/BCM pins are "Common-Mode Input for Bidirectional, Differential A2B Line Transceiver". On the evaluation board schematics, I see that these pins are AC-coupled to ground with capacitors, but are subsequently…
