Is there a simple way to generate a 200Hz sine wave? I'd like something with no tuning involved, 1hz accuracy, powerable from 2 to 3V. I believe harmonics are okay, but I dont know how to quanitify them. They should be quiet enough to not be audible when listening to just the tone on headphones. The cost of the circuit needs to be less than 50 cents.
