Hey
I need some help for my project.

I need to have a square wave and a triangle voltage...
I like to use the "standart opamp circuit" im sure u guys know what circuit i mean...

So now my problem... The supply voltage is variable from 20-60Vdc and the peak of the output signals should be arround the same value as the supply voltage...

May one of u guys can help me find a solution....

Thanks

PS: Sorry for my poor english... Im not native in english...

Marcel, is this for personal use or is this for a company?

You might consider using amps such as: Texas Instruments OPA452TA which supports 20-80V supply voltage, or Linear Technology LTC6104HMS8#PBF which supports 4-60V supply voltage.

National Semiconductor has a nice application note "here":http://www.national.com/ms/LB/LB-23.pdf on how to build triangle wave and square wave generator circuit using op amps. This might be a good start.

i think you must visit this web site

http://www.ecircuitcenter.com/Circuits/op_tri_gen/op_tri_gen.htm

and work to that circuit to get a aquaer wave and sine wave
