• AD5546: reference input circuit

    Q 

    If the reference input is an AC signal as stated below in figure1 and I still
    would like a bipolar output, but I don't use the U2A OP2177, and float the R1A,
    ground the RCOMA, then apply AC signal directly to VREFA. Is this  connection
    ok or…

  • AD5446_SFDR

    1. 在AD5446数据手册中，只有fout=50KHz和20KHz下有一个SFDR规格。而fout=500KHz下则没有。我还查看了AD5449数据手册，它在500KHz fout下提供了此规格。如果有的话，能否提供AD5446在500KHz下的SFDR？或者，能否就以下要求给出一些器件选型建议：500KHz fout下的SFDR大于70dB、分辨率为14/16位、Fs>1MHz？

  • set up ad5541 support for imx6sx SOM (device tree)

    I need to set up an ad5541 IC connected to the system SPI bus using the device tree.

    According my current linux kernel (4.1.15) the IC is supported by the ad5446.c driver. I already checked the docu from AnalogDevices.

  • AD5553 Operating Temperature

    I see that the operating temperature of the AD5553 is -40 to 85C.  Is that air temperature around a mounted device on a standard board or is that case temperature?

    Thanks,

    -John

    Hi John,

    The operating temperature ranges seen on the data sheets are the…

  • Analog Current Output with in the pA or fA range

    Q 

    For our optical oxygen sensors we use currently the ADuC7023 in combination
    with AD5695 for analog output with 0-2.5V. An industrial customer requests now
    an analog current output in the range 0-100nA (yes, nanoampere!). Could you
    advise any solution…

    再次测试发现AD5446表现非常连续和有规律，难道是AD5543本身的问题？

  • RE: Linux device driver for AD5693

    Hi,

    I'm sorry we do not have a driver for this part at this moment. The part seems to be similar to quite a few parts which have drivers, but just not close enough that it could be supported by the driver. In terms of simplicity of a 1 channel DAC the…

  • RE: Controlling an AD5790 using RPi3 & linux iio driver

    I don't think that you need to patch the driver in order to can probe it using device trees.

    The first issue is your compatible string:

       compatible = "adi,a5791";

    Try "ad5791".

    You need to also define the "vdd" and "vss" regulators…
