• AD5544 Settling Time Question

    I am trying to compare the AD5544 current mode DAC to the AD5686 voltage mode DAC and I was needing some help understanding the settling time for the AD5544. For the AD5544 the output voltage settling time is 0.9us to plus/minus 0.1% of full scale, with…

  • RE: EVAL-AD5370 Overlay

    I've successfully enabled the driver and compiled a kernel, but I'm very confused on how to make the overlay and enable it to be able to use the driver.

    This makes us assume you are using this with a Raspberry Pi.

    Is this correct…

  • RE: AD568x true DAC architecture

    Hi Michael.

    I understand your position but as for me I prefer that structure would be described as it is in reality. Some differences between two discussed structures may be observed in noise performance, modulation bandwidth code related effects, stability…

  • RE: supply voltage vs. output/input voltage on DACs and ADCs

    Hi Jon,

    You can supply the device using a 4.8 V supply but you will be limited to 4.8 V at the output if using the internal reference and a gain of 2..

    If you are looking at using an external reference then please use the AD5686 and not the AD5686R…

    Hi Mark,

     

    Problem still not solved

  • RE: AD5680 update anomalies

    Hi,

    What load conditions are you operating under? The Maximum settling time for the device is 85 microseconds assuming the line capacitance is less than 200pF and the resistance is more than 2kOhms. Could you provide a schematic we can take a look at…

  • pyadi-iio support for ADRV9002

    Hi!

    I'm trying to access a ADRV9002 board through pyadi-iio library and libiio with the current (and hopefully newest) versions:

    >>> iio.version
    (0, 21, 'b23a03b')
    >>> adi.__version__
    '0.0.5'

    But I get this error when…

  • AD5686R/AD5685R/AD5684R transfer function error?


    Revision C of the AD5686R/AD5685R/AD5684R datasheet shows the transfer function of the device as

    Vout = Vref * Gain * (D / (2^n))

    It then goes on to say that the valid code ranges are as follows:

    0 to 4,095 for the 12-bit device.

    0 to 16,383 for…

  • Eval-ad5370 device tree questions

    Hi,

    I am new to AD537x DACs. Currently I want to control the evaluation board eval-ad5370 via SPI directly with my Raspberry Pi 4. I built the kernel (wiki.analog.com/.../raspberrypi) and add the Linux iio drivers for Eval-ad5370 via "make menuconfig…
