Can you suggest the alternate IBIS model which can be used for AD7671 for SI analysis ?
We also require Rise/Fall time for AD7671.
I am using AD7671 in my project with ADSP21369 processor . I have configured adc as per data sheet.It is in offset binary mode.when I try to read the data from rxspi.
the digital output obtained is not constant .Is there any delays we should…
I am a fresher who started to work in this field. my requirement is to interface AD7671 with ADSP21369 using SPI. Could you please tell me the steps how should I start my work. I am not understanding how to start. atleast a rough idea what are…
I need AD7671 IBIS model, but I can't find it on the website.
If you don't have the IBIS model,
please tell me ADC part number with IBIS model which has a similar I/O spec…
When I use AD7671 to convert signal (1Hz to 1kHz), I found steps in the output.
Attachment figure 1 is the waveform, where green line is input of AD7671;yellow line is the output of AD7671 (a DCA output, the DAC operated well).
I connected to input 0 V - code from AD7671 is 32463. It is fine.
But when I repeat request the code is
32463 32591 32591 32463 32591 ....
32591 - 32463 = 128 - Where is low signif. bits ??
I checked with serial and parallel data mode.
I am using AD7671 ADC in one of my project. I accidentally supplied analog signal(13V) to the ADC without powering the ADC. Now this adc is behaving abnormally. I am able to get accurate data till 2.5V input after this range the ADC doesn…
As I am performing SI analysis for one of the processor boards. We need IBIS model for AD7671
Please provide us with the IBIS model for AD7671.
I am not able to find Gain error of AD7671 in the datasheet. Can you provide the value? I need them for Error Budget
Is there a way to calculate them from other parameters?
I am currently working on interfacing AD7671 with ADSP21369 using SPI communication protocol. Here ADSP acts as master and ADC as a slave. I have configured all the spi registers, srus. I am struck how to use ADC's CNVST pin to read the converted…
