Variable amplitude Sine Generator IC

kiamzattu

Hello everyone
Does anyone know of an IC that can generate Sine wave of different amplitudes? I'm talking about the peak value. Is there any IC that can output different sine wave(peak values) depending on the input condition?
some people told me of ICs that can vary amplitude using a POT at the input. But i dont want to do it manually. is there any way of adjusting amplitude without using a POT?
