This will help prevent confusion since replying members will be less likely to be confused. 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.

That is because in both cases the ground reference is not a direct connection to ground. Can I use a pen or mechanical pencil Posted by coonsaa0 in forum: Nov 13, 4.

Oct 29, 7, 3, As for the power supply, the opamp is actually being operated as an opamp rather than a comparator. Nov 13, 1. Yes, my password is: I am not great at reading datasheets. The voltage you measured across C was around 15 volts. Posted by Gamedojo in forum: Nov 13, 9. No, create an account now. Nov 16, 1, Posted by spidermanIIII in forum: First off it was probably not necessary to start a new thread since members are going to be a bit confused between the two.

Datassheet causes the output of the opamp to go positive datasehet drives the base of transistor Q which in turns drives the base of Q positive.

The trick to the -8volt regulator c14558c 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.

Motion-Activated Trail Camera In this Teardown Tuesday, we are going to take a look at the inner workings of a trail camera! Nov 13, 6. I really do not care if one of these is datashee best choice. I have it working. But would want to run ti by the folks here anyway. A Non-Invasive Glucose Sensor Researchers believe that sweaty armpits may be the answer to both detecting and controlling diabetes. Jul 17, 22, 1, Actually the voltage measurement I would like you to make is the voltage across the terminals of the capacitor.

Nov 13, 8. You placed your DVM probes on the satasheet and c1485c terminals of the capacitor and the voltages you posted are the ones you read. You May Also Like: This action pulls the positive end of the transformer secondary supplying the 15V DC down slightly.

Just so that I am clear. I could probably ramp the dataeheet up to 15 VDC if that is recommended. Apr 5, 18, 3, Here are my voltage readings for the -8 section. Is this a good enough test for U A and B in t his schematic? You might find that one or more of the transistors connected to the output is shorted.

I suspect that the op amp in the circuit is bad. Discussion in ‘ General Electronics Chat ‘ started by spinnakerNov 13, Dstasheet line, compare the datasheets of the op amps for compatability.

Nov 13, 5. Datahseet 13, 7. It is a CC. Could this finally be the dawn of room-temperature superconductors? That can be remedied.

Can we use a tristate buffer dayasheet place of voltage level shifter? I am trying to fix my Tek scope power -8 and power supply. Can I use a flyback transformer in a forward topology? If you imagine that the load on the -8V output increases then the -8volt output would drop slightly toward 0v.

I can’t seem to find a datasheet for a CC, but the pinouts on the schematic agree with the above opamps. Do you already have an account?

I have included the PS schematic below. What voltage do you measure across capactors C and C? Datashret results in a restoration of the -8volt output so that the droop due to the increased load is cancelled.
