So I spoke to the designer and I believe the model you provided in your thread above is accurate for SDA in that there are protection diodes in the SDA pad for when the device is to be a SPI part. The problem is that POWER must be applied for…
Could you please recommend ADI's IC as the device reset for AD7091R-5 ?
I read datasheet Rev. 0 | Page 31 of 34.
>6. The master sends the first data byte (0x03) to the configuration register, which selects the command mode.
But I think 0x03 doesn't mean a command mode.
AUTO and SRST are set by 0x03.
I was disappointed to find that there's no Linux driver available for the AD7091R-5 part our hardware team have selected. I'm trying to adapt a driver for a similar part, but I'm having trouble getting a sensible conversion value out of the device.…
The digital interface for the AD7091R-5 is I2C vs SPI for the AD7091R-4.
I'm DFAE in Japan. Our customer connect AD7091R-5, AD7415 and others with I2C interface in the system. When the system is powered off, both SCL and SDA are into LOW. His end-user suspects that there is an IC in his circuit that pulls those signals…
Unfortunately, we don't have it. At this moment, we are supporting AD7091R and AD7091R-5 (4 channels but I2C) - Linux Drivers [Analog Devices Wiki].
until now I'm not able to use the AD7091R-5 with internal reference of 2,5V.I'm sending this bytes to the AD7091-R to configure it :\x02\x06\xC1\x01\x0F\x00meaning config reg 0x02 is set to 0x06C1 -> CMD Mode = 1, -> Software Reset…
I am starting a small aquisition Circuit with the AD7091R-5. I only have IIC w/o Reset line. I wondered if the Reset can be connected to a R and C in series:
Or should I use a reset circuit for this application?
