I have a circuit running from a +/- dual rail supply. I want to produce a square wave signal voltage (driving 10k resistance) about 22 kHz which gives me a positive +/- signal relative to ground.
I can build the 555 with an almost 50% duty, but it is the negative part of the output I am struggling with.
I have searched for ages for a way to do this with a 555, but not come up with anything that seems to do it.
Is there an easy way to achieve this? Any suggestions most welcome!
