AD5541/5542 Digital-toAnalog converters from Analog Devices

[ampm]

Dear Friends,

Does anybody have experience programming in Labview the AD5541 or AD5542 boards (Digital-to-Analog converters) from Analog Devices (http://www.analog.com/en/prod/0%2C2877%2CAD5541%2C00.html)?
LabView code examples or description of the general approach to this task would be much appreciated!
My PXI system has NI-6534 board which I can use for digital output. But I need to perform Digital-to-Analog conversion by the remote AD5541 board.
Is there a way to do this?

Thanks in advance

Hi Ampm,

Thanks for the datasheet for this device. You will have to write the entire waveform in order to communicate with it. This is: CS, DIN and LDAC generated with a digital waveform and export the clock to the DAC.
To write a digital waveform to the card I would suggest to start with the shipped example "Generate Values.llb\Cont Write Dig Chan-Burst.vi". These examples are installed when you install the DAQmx driver.
Hope this helps,

Thanks for your reply!

..Now I am stuck with the task of converting a number (digital value) into a sequence of bits for the 5541 chip..
Can you suggest a way of doing this? Any code example?..
I have an idea how to do this in MathScript but MathScript code runs veeeery veery very slow.. I hope there are other known approaches to this problem.

Thanks for your help!

Hi Ampm,

This is more like a software trick and I think you mean something like the attached VI?
This is a native VI in LabVIEW and I hope is doing what you are asking.

Good luck,
