I'm looking for a way to take differential inputs at once with a range of -15 to +15 volts. I usually work with PICs but they only have unidifferential inputs with a 0 to 5V range. Ideally I'd use some NI-DAQ with Labview, but that's kinda out of my personal budget, while PICs and ICs are around $3-$5 Anyone have any ideas?
