I would like to use AD7995.
So, I have a question.
Data is transferred by pulling up VDD at 4 V and SCL / SDA at 3.3 V.
In this case, does the SCL / SDA start running after the 4 V power supply rises to 3.3 V?
(Let me know if you need it in English)Hej, har problem med en AD omvandlare, se bifogad excelfil. Har ett invärde, till kortet, på 1,614 volt och efter spänningsdelning har AD-omvandlaren på sin ingång, pin 3, 0,588 V. Värdet vi får ut varierar i tiden…
I have some questions about AD7995.
Please see the attached file.
Could you give me some adovice?
Thanks in advance.
I'm having trouble getting the data I'm expecting to see back from the ADC7995. Reference voltage is set to 5V, channel 0 is connected to the signal whose level I'm interested, and the other channels are tied to 5V. My I2C interface is running at 400kHz…
Can you tell me how to reset the sequencial channel reading of AD799x?
For instance, according to the datasheet, when D7 to D4 bits in the configuration register of AD7995 are all set to 1, AD7995 converts from CH0 to CH4 sequencially until the user…
2. After the master has addressed the AD7991/AD7995/AD7999, the part begins to power up on the ninth SCLK rising edge. At the same time, the acquisition phase begins. When approximately 0.6 µs have elapsed, the acquisition phase ends. The…
I was able to reproduce the issue. Please try the following fix iio: ad799x: Fix buffered capture for ad7991/ad7995/ad7999 · analogdevicesinc/linux@e7bf30e · GitHub.
I simply could not reproduce it earlier due to a configuration error, sorry for…
Currently we do not have IBIS model for the AD7995. Here is the link of the IBIS models that we currently have. A number of ADC are available. What is your type of application that you want to simulate?
Thanks for the valuable information.
Regarding this development I still have some design considerations to make. We need to measure 3 to 5 strain gages (the exact amount is not yet known and is to be determined by a mathematical model…
