Hello Gurus I need to buy an external current bias chip and provide it to my PCB designer. I have never done this before, what are the specifictions I need to look at before I buy one and which company is recomended? I need a tunable current bias chip. So how do I go about with this. I would also like a rough estimate on the amount of currents Ill be looking at from a current chip.It would be great if it is in the micro amps range. Your help will be appreciated. regards srivats -- P.Srivatsan Graduate Student ECE Dept,North Carolina State University http://www4.ncsu.edu/~spartha2/ -- I have no special talents.
