• ADAU1701 vs. AD1941

    Hello,

    I have to expand a digital-radio-transceiver for automotive applications by a DSP. The DSP has the task to equalize music by using various profils (e.g. rock, pop, flat, bass enhancement). The choice which profile will be used should be controlled…

  • AD1941 I2C Reading Problems

    Hi.

    I have developed the micom control program using AD1941 Sigma DSP.

    I developed a custumized AD1941 board and it is working very well.

    But, the only one problem is the I2C data read. (There is no problem when I2C data writing.)

    I tried to read…

  • RE: Hi, how can I get a sigma studio soft  key?

    Different subsets of algorithms run on different SigmaDSP processors. Some algorithms are not available on all processors due to memory limitations.

    The reverb algorithm is available on the AD1940, AD1941, ADAU1442, ADAU1445, and ADAU1446 SigmaDSPs.
