Hi Everyone,
Just joined.Well, the issue is i am taking on a project that will require detection of very small changes in currents(an order of micoamperes) and make decisions depending on the magnitude of change.I am thinking of using the ADC(analog-to-digital) of a PIC to detect the magnitude of change.Is there a device i can use for this or is my idea the best option?
Thank you
You are looking for changes of a few microamps, but is that a change from 10uA to 11uA, or a change from 1.000000A to 1.000001A ?
Both represent a change of 1uA, but the first case is easy, the second maybe needs a bit of thinking about.
You could start by answering my initial question, you are looking for changes of a few uA, but how much of a change in current do these few uA represent?
