• AD7949 input configurations

    1.
    In the datasheet page 19 (input configurations) we see in figure 29-A the
    single ended inputs are reference to ground and COM pin is NC. In our board we
    connected the COM pin to ground but configured the DC to single ended. Is it
    allowed?…

  • AD7689 and AD7949 disable internal clock

    I'm wondering if the internal clocks in these devices are active only for the
    conversion or if it is possible to disable them using one of the operating
    modes?

     

    There is no internal clock for AD7689 and AD7949. You have to provide an
    external…

  • AD7949 occasional invalid samples

    Hi,

    I am working on a system that uses 5 AD7949s connected to a single SPI bus, clock running at 16MHz. When reading the ADCs, we are using the RAC (read after conversion) method to return samples.

    Our sample rate is very low; only 50Hz. The clock was…

  • AD7949 Data sheet

    Greetings all.

    Page 22 of the data sheet (Rev F) states: "However, due to the possibility of performance degradation, digital activity should occur only prior to the safe data reading/ writing time, tDATA, because the AD7949 provides error correction…
