opamp with variable supply voltage

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 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
