  • ADAU1442 hardware design

    Hello All,

    We are developing a product where we need to interface 6 I2S ports to the processor. Due to limitations in number of channels on the processor side,  We decided to have a dedicated Codec/DSP to collect all I2S port's data and stream it on one…

  • ADAU1442 channel assignment

    Hi,

    the ADAU1442 is designed as a multi-stereo device by pairs of inputs and outputs and the datasheet documentation advises to use them as pairs.

    We would like to use the channel lines of the pairs to be routed as single lines (means f.e. the left…

    I'm working with the ADAU1442. I have developed my own prototype DSP_Board with the ADAU1442. See the PDF.

    Everything was working but suddenly the Master Clock doesn't work. So there is no frequency on XTALO and XTALI. Before there was a…

  • An  issue about ADAU1442

    Dear Engineer,

    I am studying the part ADAU1442, and i plan to use I2C to control ADAU1442, changing the parameter (EQ, volume, route)at the same time.

    I wonder whether or not there are formula for volume, just like EQ's.

    Thanks.
