In all the circuit will be active for about 1500ms, not really seeing this as precision, maybe I am going about this wrong.
I am looking for a cheap (in BOM $$$) way to create a carrier wave for a NFC like communications device. It is inductive coupled - think air core transformer. The shape of the "sine" wave is not super critical, just trying (assuming it is important) to remove some of the harmonics from a square wave source.
Again, at production the circuit will be tuned. I am simulating in spice to catch current and other issues going forward.
I would ideally like to get the TI lib working. So far I have been finding random 555 libs, but none of them match the TI datasheet.
