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.

EHILLEL820,
You absolutely can read from channel 0 to channel 3 (1-4) in sequential order. Assuming you are using the AD7091R-4, you can simply program the channel register (ADDR = 0x01) with code 0x000F to enable channels 0 to 3 for conversion.
If you…
is there any simulation model for AD7091R ? I want to use a FPGA to connect to AD7091R to get data
Hi,
By using external reference would it increase measurement accuracy ?
If so, which reference IC is recommended ?
Hello
I'm trying to set up communication with AD7091R-8. In setup I send following SPI command: 0X0CFF, 0X08FF, 0XFFFF, 0XFFFF, 0X00FF. Then I periodically send 0X0020 and I'm trying to read channel 5. I'd like to read one channeland them sequential readings…
Hi,
I have a AD7091R application which is outputting 'improperly justified data' at lack of a better description. The first bit shifted out doesn't appear to be the MSB, rather the results of a previous conversion - the 8th bit shifted out appears to…
Hello
Please let me know about Ron of multiplexer. in AD7091R-8.
For example, the datasheet of AD7329 which the device is like AD7091R-8 ( Muxout -> ADC in) describes below
MUXOUT+ Capacitance (datasheet P. 6)
Resistance including on resistance…
Hi
I'm a DFAE in Japan. Our customer give us a question. There is a MOSFET inside SDA pin of AD7091R-5. On the other hand, is there NO MOSFET inside SCL pin of AD7091R-5? According to Table 5, we couldn't see Open-drain output about SCL as follows.…
Hello,
I did send my question in this discussion:
As we are having similar issue. Basically initializing the ADC with 66 pulses of CONVST does not seem to work...
I can provide all probing or logging if needed.
Hope someone…
