Hello Friends,
I am trying to make a 1khz freq oscillator using op amp... to generate sine waves using ic555 or just opamp... can someone give me a working circuit diagram.?

 

Hello,

The shown voltage range of 2 - 12 Volts is very wide.

The following PDF's from TI will give you a lot of information on the use of opamps,
including several oscillator circuits:

it also helps me generate a sine wave right?

 

Hello,

There is a special PDF on sine wave oscillators:

The easy way to generate a 1k sine wave is an XR-2206 chip, but it won't run on 2V. Nothing runs that low.
