Will the conversion output be available along with 14 clock SCLK of the same channel.
Or the data available on Dout is the conversion value of previous channel during 14 SCLK .
With best regards and wishes
Apologies for the delayed response.
It is still best to read the serial interface in detail for because some of our parts have configuration latency. Basically, we have configuration latency (channel selection, etc) and sample latency (output delay, which I believe is your concern). I mention configuration latency because we do have parts with no pipeline delay but data the configuration is written in phase n-1, converted in phase n, and then read back in phase n+1. This is not a pipeline delay as associated with the high speed converter products.
As for the AD7266 channel/input configuration – the input configuration is set during phase/conversion n-1. The sampling edge during phase/conversion N is relative to the configuration set in the previous phase. The /CS in phase N is the sampling point – the conversion result in phase N is relative to the sampling point in phase N and hence there is no conversion latency.
Sorry it is AD7266
I moved this post to the Precision Converter community, someone here should be able to help.
I went through following discussion .
AD7357 states clearly that it the data is from previous conversion but how do you know if it is from same conversion or previous unless we read in detail .(Should we take it as same channel unless described )
Could you please let me know a key word for those device which output on the same cycle .
Does" There are no pipelined delays associated with the part " relates to this working because the data is been output during conversion time .
I am looking into this. I'll get back to you soon.
The output data clocked for the AD7266 is for the current conversion. You can see this in figure 31 on page 17 of the AD7266 datasheet where the SGL/DIFF pin is set for both the acquisition and conversion time. The no pipeline delay feature only means that the conversion results are available immediately after the conversion is complete. I don't think there is a general keyword for our parts where conversion data for the conversion is output on the same cycle though. This is specified per datasheet.
Can you share what other specifications you require for your application so i can help you choose your part?
Let me get this correct , The data is available for the current conversion right .
Please let me know with regards to the following statement
"The no pipeline delay feature only means that the conversion results are available immediately after the conversion is complete"
But this part output data during conversion , so can we take this Keyword that No pipeline delay = current conversion result on the same cycle.
