single input analog to digital DAQ


Thread Starter


I need a diagram or a product that has only one analog input, convert it to digital and has a pc interface, possible serial of paraller port

im working on a project that require a DAQ, but DAQ with a high speed sampling rate is rather expensive and i only need one input which takes analog frequency signal and convert it to digital for processing with a pc.

please if anybody knows a solution do email me at [email protected] or reply to this post

Your message is unclear. Are you measuring voltage or frequency? What acquisition rate are you looking for? What resolution and accuracy? What is the signal range? What sort of signal conditioning do you need? Is this a student project where you are building everything yourself, or is this supposed to be used in a real industrial application?
