Nov 13, 8. It is a CC. The voltage you measured across C was around 15 volts. What voltage do you measure across capactors C and C? The trick to the -8volt regulator stage is that Q is acting to control the positive-most end of the 15V secondary transformer winding so that it is exactly 7 volts positive when measured with respect to ground.

Can I use a flyback transformer in a forward topology? Nov 13, 6. Jul 17, 22, 1, I darasheet trying c148c fix my Tek scope power -8 and power supply. This results in a restoration of the -8volt output so that the droop due to the increased load is cancelled.

This will help prevent confusion since replying members will be less likely to be confused. As the -8volts drops the positive input to the opamp begins to go positive. Is this a good enough test for U A and B in t his schematic?

Bottom line, compare the datasheets of the op amps for compatability. Do you already have an account? Motion-Activated Trail Camera In this Teardown Tuesday, we are going to take a look at the inner workings of a trail camera! That can be remedied.

Could this finally be the dawn of room-temperature superconductors? I could probably ramp the voltages up to 15 VDC if that is recommended. A Non-Invasive Glucose Sensor Researchers believe that sweaty armpits may be the answer to both detecting and controlling diabetes.

Here are my voltage readings for the -8 section. Nov 16, 1, I have included the PS schematic below.

But would want to run ti by the folks here anyway. Can we use a tristate buffer in place of voltage level shifter? This action pulls the positive end of the transformer secondary supplying the 15V DC down slightly.

Jan 28, 9, You might find that one or more of the transistors connected to the output is datzsheet. Nov 13, 4. I went out a purchased a datashedt of op amps from Radio Shack and built a comparator like the first one on this page. I have it working. No, create an account now. Spinaker, You will notice that I have merged the newer post with the older post since the second thread was datasueet continuation of the first. Posted by Gamedojo in forum: As for the power supply, the opamp is actually being operated as an opamp rather than a comparator.

If the opamp is in a socket, why not try testing it on the bench? I suspect that the op amp in the circuit eatasheet bad. 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. I started reviewing the lessons on op amps on this site because I think the problem with my Tek scope power supply is a bad op amp.
