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…
The on resistance of the multiplexer with a 5 V supply is typically 50 ohms, while with a 2.5 volt supply the on resistance typically increases to 100 ohms. This is outside of the resistance mentioned on page 19 of the datasheet. By the…
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…
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…
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…
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.
