![]() so 11.3V to 10.7V.ĪLSO! I want to thank you guys for your feedback, I found the issue and solution to my design!! I have revised my tolerances to be within. I have been searching for a few days for a solution. I just need one reliable solution to generating this bipolar 25kHz square wave. How can I scale a 0 to 5v 25kHz square wave into a bipolar +6 to -6v square wave? It seems the frequency is too high to run astable? I am going to try to input a 25kHz waveform from an Arduino and scale with the op amps today. but was puzzled the 072 did the same thing. I would expect this on the 741 (.5v/us slew rate). Now, I have tried 741 and TL072 op amps to run an astable oscillator, but the closer I get to 25kHz, the more they look like a sawtooth waveform. So It needs to be scaled back on the other side from a bipolar signal back to a 0-5v 25kHz square wave. I then need to read the ouput of that signal with another arduino. Or I can use an Arduino to generate the 0 to 5v frequency and then scale and offset it. ![]() I can do this with a standalone oscillator (only need one frequency). ![]() I need to produce a square wave of 25kHz and 12v with an offset -6v (+6v to -6v) at a 50 percent duty cycle. ![]()
