What is the DAC type on PCIe 7852r vs PXIe 7857r

Hi!

We have a computer with the PCIe 7852r board and a separate PXI system with a PXIe 7857r board mounted.

They have both got an 8 channel DAC which we are using for experimental purpose.

I would like to know which DAC chips are used on these two systems and if they are the same?

I think the PCIe 7852r uses the Linear Technology LTC2641/LTC2642 DACs. I cannot find the chip on the PXI board.

 

Thanks for you help!

 

BR,

Alex

Any why the actual DAC chips are essential than the board connector level specifications?

Hi Santhosh,

We use the DACs for research purpose, and remapping the nonlinearities (which are DAC archetectural dependent) is a time consuming process so if we don't need to do, it is very nice to know.
