Circuit Board
can anyone tell me how to make a Analog to Digital circuit on circuit board instead of using PC parallel port ?

I dont want to use parallel port using pc , i want to use electronical components on circuit board , please help.

It’s not an either or situation. PC parallel port is not a prototype platform, it’s a way of sending data into or out of a PC.

So yes, you can build a AD on a PC board. Look at the Analog Devices web pages and pick a suitable AD for your application, or at that National Semi web pages. There are thousands.

Get the data sheet. They will usually contain a schematic. Get the parts and go from there.

But what are you going to do with the 8 or 12 or 16 bits of data (depending on which AD you pick) you get from it. You can get 16 bits every microsecond on some parts. That’s 2 million bytes every second. You need to send it somewhere…. perhaps to the PC parallel port?
