Gajind But would want to run ti by the folks here anyway. Can I use a pen or mechanical pencil Posted by coonsaa0 in forum: Jan 28, 9, Nov 13, 1. I went out a purchased a couple of op amps from Radio Datasgeet and built a comparator like the first one on this page. This causes the output of the opamp to go positive which drives the base of transistor Q which in turns drives the base of Q positive.
What voltage do you measure across capactors C and C? That can be remedied. Can U use 2 transistors in place of a relay to switch 2 different voltages Posted by icadj in forum: Xc, create an account now. I am not great at reading datasheets. Jul 17, 22, 1, Nov 13, 8. Nov 13, 2. If you imagine that the load on the -8V output increases then the -8volt output would drop slightly toward 0v.
You might find that one or more of the transistors connected to the output is shorted. Nov 13, 3. Your name or email address: Nov 16, 1, Nov 13, 6.
Spinaker, You will notice that I have merged the newer post with the older post since the second thread was a continuation of the first. You placed your DVM probes on the negative and positive terminals of the capacitor and the voltages you posted are the ones you read. Would one of these work for now? As the -8volts drops the positive input to the opamp begins to go positive. I have included the PS schematic below.
Here are my voltage readings for the -8 section. Nov 13, 4. I could probably ramp the voltages up to 15 VDC if that is recommended. It is a CC. Nov 13, 5. I am trying to fix my Tek scope power -8 and power supply.
Is this a good enough test for U A and B in t his schematic? This action pulls the positive end of the transformer secondary supplying the 15V DC down slightly. Could this finally be the dawn of room-temperature superconductors? That is because in both cases the ground reference is not a direct connection to ground. Actually the voltage measurement I would like you to make is the voltage across the terminals of the capacitor. Nov 13, 9.
Bottom line, compare the datasheets of the op amps for compatability. All About Circuits I would have cc know the part number to answer your question with certainty. Quote of the day.

Could this finally be the dawn of room-temperature superconductors? Just so that I am clear. As for the power supply, the opamp is actually being operated as an opamp rather than a comparator.
