Serial ADC

[KBG]

Hi,
Which is better to use - Serial ADC or a ADC with output on 8 pins ?

Thx in advans,

Depends on what you are connecting the ADC to.

Data transfer could be higher with a parallel interface, but thats not
always true.

good luck

Depends on what you are connecting the ADC to.

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.

always true.

Why ? what is the reason behind this ?

Yes, i understand the reason for this.

but thats not always true.

But , Why is the parallel interface not always higher ?

So, i can jump between serial & parallel at this time.

Its obvious, 8bit vs 1 bit per read clock.

The problem is getting a chip that's 8bit or 16bit parallel.

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.
