Apta,
The next step is to look at how you are connecting things to the ADC and the amount of settling time between conversions. Can you please share any additional circuits you are using to condition the signal(s) you are attempting to measure. In fact…
大家好 最近在调试AD7699 用FPGA控的 发现使用内部排序器后 采不到正确的电压值
后来关闭排序器 手动调整通道号 采集的就是正常的了
请问在使用内部排序器时 需要注意哪些呢
I get wrong temperature value when I read out the internal temperature sensor in the AD7699.
The environmental temperature is about 25 degrees Celsius. According to the data sheet should the voltage be approximate 283mV. I read out 262,5 mV (dac value…
Hi, I have a couple of question about using an AD7699;
Some background: Basically I'm developing a product where we need to sample two channels of the AD7699 at very specific time intervals (around 40uS), so I'll be using an timer interrupt to control…
Hello,
To evaluate AD7699, I installed its evaluation software(PulSAR to EVAL-CED1Z software) from ADI website ( http://www.analog.com/en/products/analog-to-digital-converters/ad-converters/ad7699.html#product-evaluationkit ).
When I executed the evaluation…
Hi,
Any body have Linux driver for ad7699. I could not find driver in Analog devices website or in Linux kernel tree. Please help me to acquire data from ad7699.
Do I need to use a buffer for the Analog Inputs if I am reading DC Values?
I am using an AD7699 in general timing without busy indicator, readwrite during conversion, configuration register = 11110011110111.
The three lsb are always equal to 1. (Even after replacing with a new part and validating timing)
Any thoughts?
James…
Dear Sir/Madam,
I am using AD7699, and have some issues about the EVB.
What the function of R46 of ADC BUFFER, does R53 and C58 configure a low-pass filter.
What is the functio of R26、C38、R28
