Hi.
Which integrated circuit is designed to output a preset plain sinewave and nothing else ? 1KHz is OK. This is about which IC, not about which schematic circuit to make.
Supply in, preset components, AC out IC.

None that I know about. The reactive components would still need to be off board, so you would still need a circuit.

Seems like the is no present chip that meets the requirements. Both the XR and the ICL are out of production for a long long time. That might be because nobody has a compelling need for such a thing. If you need such a thing my suggestion would be a very fast processor with a DAC and a lookup table. Might even be able to find one in an 8-pin package.
