Part Number: ADS8699 Dear Specialists,
I want to use the ADS8699 as SPI master, and MCU SPI as slave. From the datasheet, I found ADS8699 RVS pin can send clock as SPI clk signal, and RVS is from i nternal clock (Figure 6-8).
My question is:
After the CS…
Part Number: ADS8699 Other Parts Discussed in Thread: REF5045 Hi TI Technical Support Team,
I have designed a small 4 layer board with 2 18bit 100kHz ADS8699 and I am planning to use it to read voltage and current values from the device under test. The…
Part Number: ADS8699
Hi TI Technical Support team,
With the help and suggestions made to my previous post in this forum, I have designed a board that has two TI ADS8699 18 bit 100kHz ADC on, which will be used to measure analog voltages between 0 and…
Part Number: ADS8699 Other Parts Discussed in Thread: ADS8681 Dear Team,
My customer is designing a board with ADS8699 and TMS320F2837xD C2000 MCU.
Do we have any timing examples of correct SPI communication with ADS8699, such as oscilloscope screenshots…
Hi Dale,
Thank you very much for your strong supports.
I will tell the suggestions to the customer. It is very helpful for them and me.
Could I ask you a request?
Could you please consider modifying the current ADS8699 datasheet(SBAS777B) to clear RVS…
Part Number: ADS8699 Hi,
regarding the internal reference of the ADC I do find some drift figures. However I am primarley interested in the long term drift of the internal reference. Does TI provide any figures regarding this topic? I am working on a…
Part Number: ADS8699 I'm getting semi-repeatable voltage conversions on a 9v battery. I don't think a battery should be this noisy (note the 9333 mV reading). I'm at the point where I don't have an idea of where the problem might be (program or electronics…
Part Number: ADS8699 Other Parts Discussed in Thread: ADS8691 Hi.
We are testing out an ADS8699 ADC and I have two questions:
My understanding is that if one uses the default values for range, etc., one should be able to read out the ADC values at +/…
Hello user5841294,
After power up the ADC, all bits in DATAOUT_CTL_REG register are zero, the 32-bit output data on SDO-x will only include 18-bit conversion result and the rest bits will be all zeros, so you got right information on SDO-x. The default…
