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?
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
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…
Hello,
We are working on analog module.
AD7699 seems to work for design. However I have following queries:
1. Once the ADC sequence register is set to give the channel output in a particular sequence using sequencer, is it required to reprogram sequence…
Hello!
My name is Nikolay Krotov. Our firm have some AD7699 and we try them. There is a problem . By datasheet it is 16 bit ADC. We try slowly (constant) signal. So we take data from ADC with 0.1sec period.
Regime ADC – external REF = 5.0v. Frequen…
