• ADAU1452 leakage

    Hi,


    I have some questions about ADAU1452.

    When I send CLK by external crystal to ADAU1452's XTALIN/MCLK pin.

    ADAU1452's power pin will produce a voltage even there is no power supplied to ADAU1452.

    Once stop sending CLK to ADAU1452, this…

  • RE: About SPI Slave Port of ADAU1452

    Hello, ADI Support Team

    I have an additional explanation.

    As the background of this question, I am considering to connect between MCU and ADAU1452 and other device via SPI.

    And then, SPI master is MCU, and SPI slave is ADAU1452 and other device.

  • RE: ADAU1452 SPDIF interface

    Hi Adam,

    The evaluation board for the ADAU1452 only has an optical interface and no RCA coaxial connector. However, I think the ADAU1442 and ADAU1452 share practically the same S/PDIF interface, so the same circuit should work on the ADAU1452 as on the…
