I am validating a design using a AD7091R-4 ADC and some errors are coming up. This component has been used in 12 boards, and all 12 of them are showing the same problem. Might it be due to a faulty batch?
When the system is turned ON it might…
I searched the git tree at GitHub - analogdevicesinc/no-OS: Software drivers for systems without OS for the no-OS driver for AD7091R-2/4/8 ADC and I couldn't find it there on any branch. There is a driver called AD7091R, but it doesn't support…
Could you give me your advice about value of offset error of AD7091R-4 ?
Datasheet says +-1.5mV offset error at internal reference.
What is value of offset error at 5V external reference ?
As the result of test, offset error is about 1LSB at…
For a simple SPI bus in which the AD7091R-4 and an FPGA are the only devices on the bus, is it possible to leave CS permanently grounded?
Now I'm designing my product by using AD7091R-4 and Altera FPGA.
I find the Altera FPGA's sample code for AD7091R on ADI wilki but it's only single channel and without controlling SDI pin.
So I would like to ask whether do you have…
I have a question , AD7091R-2,-4 External Reference Input range.
There is 1.0 - Vdd V in Page 3 , at dataseat
But , there is 2.5 - Vdd in Page 18 , at dataseat.
I think external reference input range is 1.0 - Vdd .
Which is correct?
Yes, an excellent solution is to take advantage of the Mux Out / ADC In feature that allows for a buffer amplifier at the output of the multiplexer instead of the traditional solution that may require a buffer per channel. The post-multiplexer buffer…
I need to do some prototyping with an AD7091R-4 ADC to verify some HW design choices. I've been searching with minimal luck for an actual example in C of setting up and using the AD7091R over SPI.
I thought I had found one via links on the analog…
