Part Number: ADS7822 Hi team,
Could you please guide me how to configure ADS7822 SPI interface? Is ADS7822 the master device or slave device? How to connect SCLK/MOSI/MISO/SS wires? Do you have reference code?
Part Number: ADS7822 Hi Team,
We would like to know the difference between ADS7822EB/2K5 and ADS7822EB-1/2K5 (-1 version).
We understand that ADS7822EB-1/2K5 (-1 version) is EOL device.
However, we can’t get ADS7822EB/2K5 so we have to use ADS7822EB…
Hi,
Thanks for the response.
CS, SCLK and Data lines are buffered. So long connection does not matter. What is "blue wire" you mentioned? I have attached the schematic for you. Note that Scope probing is just at the ADS7822 chip.
I have attached…

Hi,
Wrong data output is observed on my customer's circuit as attached.
7127.ADS7822.xlsx
"Wrong" means below;
1. DOUT goes low at the same time as falling down of first CLK.
2. The outputted data is all "0" regardless…
Part Number: ADS7822 Hi Team
ADS7822 datasheet only state the storage high temperature is 125C, but didn't have low temperature information, could you help to provide this information? thanks.

Could you confirm my TUE calculation?
I want to estimate maximum TUE of ADS7841 and ADS7822.
I'm referring the following:
TUE = sqrt(sq(Offset error) + sq(Gain error) + sq(DNL) + sq(INL…

We want to know the deviation of 3σ for ADS7822 & ADS7841.
Could you provide it about the following?
-INL
-DNL
-Offset error
-Gain error
BestRegards
Other Parts Discussed in Thread: ADS7822 Hi all,
Please let me know about DCLOCK of ADS7822.
I have questions are as follows; - How much the upper limit of CDLOCK?
- What is "fCLK"?
Also, our customer can not output the data.
Please see the…
Hi there.
I have an Arduino Leonardo, I'm trying to talk with a TI ADS7822 [1] . I've set up the application circuit per Figure 28 of the ADC spec sheet, with the exception that I'm using a 5V supply. I'm using the wiper of a pot as the input for now…
