Please log in for more thread options Hi, Which is better to use - Serial ADC or a ADC with output on 8 pins ? Thx in advans, Karthik Balaguru | ||||||||||||||||

I need a single-channel only & 8-bit type. I have just now started to design a simple circuit for a very small requirement for me. So, i can jump between serial & parallel. So, I would like to know which to select - either serial ADC or Parallel interface . Kindly share your experience here. > Data transfer could be higher with a parallel interface, but thats not

Yes, i understand the reason for this.

But , Why is the parallel interface not always higher ?

I need a single-channel only & 8-bit type. I have just now started to design a simple circuit for a very small requirement for me. So, i can jump between serial & parallel at this time. So, I would like to know which to select - either serial ADC or Parallel interface . Kindly share your experience here. Thx in advans, Karthik Balaguru | ||||||||||||||||

Most ADCs being manufactured now are serial, and these serial devices require a high speed serial port. ( SPI mostly ) Cost and size are the reason these serial devices are available. >
