How to use multiple A.D.C with raspberry pi ?

[AbhayaSingh]

As raspberry pi takes digital input rather than analog input, we need to send signal to pi as digital. Normally for one analog input, we can resolve the matter with SPI or using 8 digital pins of raspberry pi depending upon what sort of A.D.C chip is used. For our project for the power quality improvement, i need to use 12 Analog signals of voltage and current and convert into the digital signal equivalent to it, what might be the way of the interface to pi so that we can convert 12 Analog signal into the digital signal in real time and process the data of it using the raspberry pi.
Thank you.

I got a USB-1608G from [url]http:www.mccdaq.com[/url] and have done some development with it and somewhat tested its limits concerning turn-around when loading a new DAC signal. They also have ethernet-connected models. These things are a bit pricy, but really convenient to use. You can hook up 16 analog inputs and scan them various ways. My equipment is packed away for moving and I will not be able to get at it for some time, but I could send you my notes and programs if you are interested.

Yeah, i have recently looked at its price range and its really pricy(around $400). If u wish, plz provide me note and programs regarding it. I will go through it throughly. Tx in advance.

Thank you mikronauts, that's what i had been looking after. Well, i go through it and report back the problems , confusion and suggestion after going through it.
