  • AD7699: Sharing SPI bus

    Hi, I have a couple of question about using an AD7699;

    Some background: Basically I'm developing a product where we need to sample two channels of the AD7699 at very specific time intervals (around 40uS), so I'll be using an timer interrupt to control…

  • AD7699 evalution software

    Hello,

    To evaluate AD7699, I installed its evaluation software(PulSAR to EVAL-CED1Z software) from ADI website ( http://www.analog.com/en/products/analog-to-digital-converters/ad-converters/ad7699.html#product-evaluationkit ).
