Hey guys,
First post here and hoping that someone can point me in a good direciton.
I am trying to make a 20KHz Sine Wave oscillator, and preferably want to use a single supply op-amp (the project will be run off batteries). I was wondering if someone could suggest a particular configuration or op-amp for me to explore? I have tried a Wien Bridge which worked (albeit distortedly) with a dual supply amp, but did not function with a single supply (even with a reference voltage present calculated as per TI data sheet/app note). I have tried LM358 and LM324 packages.
Cheers,
Gints
