Hi all,
I have what seems like a simple problem, but I've been unable to find the solution.
I am using a PIC to generate a square wave. The problem is that the piece of equipment to which I'm sending the square wave requires the wave to cross through zero volts - so in other words, instead of a 0-5V square wave that the PIC generates, I need to make it into -2.5V -> +2.5V. Or -5V to plus 5V. It doesn't matter what the voltages are, as long as they're approximately the same, and the signal crosses through zero volts.
Is there some sort of chip or circuit I can use to do this?
Thanks in advance,
Chris C.
