• AD1940

    Hi   engineers:

                           There is a customer in China who is using our AD1940. He use SigmaStudio to configure the level detector function in AD1940 as the figure. After the configuration, export the 0_IC_1_PARAM.h header file and he do not find the Level RTA…

  • AD1940

    I am designing a system with a AD1940 controlled off a Pic24F microcontroller.

    For testing the hardware, I have a simple 4 in 4 out schematic, no processing, no volume controls.  Straight in straight out.

    I a have a 12.288 MHz master clock, with 4 inputs…

  • AD1940,ADAU1446 - Output noise

    Sirs

     

     

    Testing the AD1940 and ADAU1446 Evaluations Boards, with a simple circuit (in directly to out), just using one channel (mono), I put a 1Khz sinus at input, and check the output test pin (with no loads). Let's see the signal. I've noted a noise…

  • Problem SPI communication with AD1940

    Hi,

    I make the prototype of active crossover with AD1940 and PIC18F67J60.

    But I have  a problem that SPI communication between PIC18F67J60 and AD1940 during test prototype board.

    I made test code for PIC18F67J60 that read core register (address 2642…
