Hello,
I'm new to IIO (though have experience in other Linux drivers) and I'm setting up an AD4020 evaluation board with Zedboard and its Linux driver. I've followed instructions from the following links:

Hello everyone,
I'm currently using AD40xx ADCs connected to Zedboard through the AXI SPI Engine IP by ADI. I'm also using meta-adi 2020.1 and also checked this with 2019_R2. From measurements, it seems the sampling frequency is around 900,000…
Recently got my EVAL-AD4020FMCZ. Want to use AD4020 for single-ended conversions within [0...+5] V, but i'm not sure if i can make it without using ADA4940 or similar.
What is the reason analog inputs beeing pulling up to midscale value of reference…
Hellow! I have problem with AD4020 ADC. I use it with STM32F407 control, and it's don't answer? What i do wrong?
My code for STM32
SPI1->CR1 = (0<<0)| //CPHA
(0<<1)| //CPOL
(1<<2)| //MSTR
(5<<3)| //Baund rate
(0<<6)…
Hello,
I have been using the AD4020 eval board for a few months now. I am very satisfied with what the ADC has to offer. However for my future needs I have to integrate it into my existing PCB. The hardware for this is pretty much open source and I was…
Hi,
I wanted to externally power the AD4020 eval board. After going through the datasheet of the eval board I figured out that I had to do the following changes.
Switch SL9 for +Vs
Switch SL8 for -Vs
Switch SL7 for Vdd
Switch LK2 for Vref
On the eval…
Hi there,
I've an FMC board with 4xAD4020 on it, connected to a Zedboard. There seems to be display issue with how the channels of each individual device are shown in the tree. I'd expect one voltage0 channel under each ad4020 node, but they all seem…
I'm using AD4020 for DC input measurement by implementing Figure 36 of AD4020 datasheet. Implemented schematic is below
But i'm getting non-zero readings which gives 0.25V reading by considering only MSB 15 bits and converting same to voltage by…
