hi every one,
I have problem to run AD7091R-8, I use fpga to use this ADC but when I initialize the ADC and set the registers and then I want to read back the registers to verify them. but there is no signal in SDO pin, I think maybe the IC didn't receive…
We are using AD7091R-8 to read 3 signals on 3 channels. We are able to enable channel sequencer and read back the correct channel ID values.
However, the conversion value is not correct. If only one channel is enabled and val;ues are read, the data…
对AD7091r-8进行寄存器写，并读回都正确，唯独进行数据采集是没有输出，发出采集命令0x00XX后，sdo返回为0；对CHANNEL SEQUENCER进行写操作后，也没有输出，读CHANNEL SEQUENCER为写入数据。实在不解？
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…
HelloI'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…
I have some questions about AD7091R-8.
The AD7091R-8 has a MUXout pin.
How long settling time is necessary for output of Muxout pin after the channel register is written?
It is a question about the MUXout when the same channel is…
I have a question AD7091R-8.
【Question 1】What happens to the conversion result if I repeat the above sequence during sequencer operation?At this time, reset is not performed.
[Situation that is occurring] Search result data is acquired with…
Please let me know below about read/write of AD7091R-8
1: I would like to read conversion result of particular channel only without use of sequencer.Should I use the method described in datasheet P.35 Figure 54. Channel Sequencer Multiple Channel…
This is how to set the channel register.Which of the following two is correct? Or are they different?① First set the Address (including R / W). The lower 10 bits are set to '0' → Next Channel Register is set. For example…
Please let me know your advice about start up sequence of AD7091R-8.
I think that I set register setting as attached file after power up.
(write needed all register setting after default setting by reset pulse)
Is my understanding correct…
