Hi, electronics was a hobby of mine about 30 years ago, I'm a bit rusty.
I would like to make a device (preferably operated by a small 9V battery) that outputs a 60KHz sine wave at 5V peak to peak continuously.
Output voltage can vary by up to 10% and frequency by up to 5% total, amperage required is minimal, as one of these small 9V batteries is intended to last 24 hours continuous use.
I know how to do something similar with a 555 timer, but not sine wave.
If someone could point in the right direction, a suitable chip and it's details, with perhaps a clue or two on the wiring needed to achieve my aim I would be very grateful.
