i got d very noob(lazy ) probelm though...


can anyone help me ?? i really need an sample circuit.. using 4pcs of LM 741 op-amps..


tnx a lot

 

Are you just wanting to show how to use them?

A good circuit would be a Bubba oscillator.

Look it up in this TI abstract, chapter 15.7.4. It is simple and effective.

Sine Wave Oscillators

The 741 is a pretty old op amp, with some not so hot specs. Drop that frequency down a lot, say 1Khz.

 

tnx for d reply


uhmm i need an schematic diagram of a circuit with 4pcs of 741 op- amps..


goin' to use this for a school activity

 

Did you look up the chapter? It shows exactly that. You need to read it, then ask questions. When you say 4 pieces I assume you are talking about 4 separate 741 chips.

 

uhhmm another nooby question


about dat chapter.. i saw d circuit u pointing out... on page 19


wat does Vout(sine/cosine) mean? hehehe

 

Same waveform, but they are 90° apart. It is a trig function.
