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…
Let me check on this. I'll get back to you soon.
I have a question AD7091R-8.
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 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…
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…
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…
Thanks for the captures.
Now, I think AD7091R-8 does not start conversion with the /CONVST pusles. The cause may be AD7091R-8 doesn't recognize the /CONVST or AD7091R-8 gets latch-up in some state.
I saw the power supplies VDD=5V takes about 50ms…
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.
