Does anybody know of a current function generator IC chip? By this I mean still in production. I know you can still find some XR2206's, but we want a current IC. We need square, triangle, and sine from 0-3 volts with freq. up to 50khz. Can an op-amp signal generator meet these specs.? I have looked at schematics for these and have yet to find any specs on amplitude or freq. capabilities. Any help would be appreciated.
