I would have to know the part number to answer your datasheet with certainty. Posted by Gamedojo in forum: Do you already have an account? In the meantime, I will use the values you have measured. This will help prevent confusion since replying members will be less likely to be confused.

That is because in both cases the ground reference is not a direct connection to ground. I have it working.

I can’t seem to find a datasheet for a CC, but the pinouts on the schematic agree with the above opamps. Discussion in ‘ General Electronics Chat ‘ started by spinnakerNov 13, If you imagine that the load on the -8V output increases then the -8volt output would drop slightly toward 0v.

Yes, my password is: I really do not care if one of these is the best choice. Here are my voltage readings for the -8 section. This results in a datashewt of the -8volt output so that the droop due to the increased load is cancelled.


Nov 13, 4. Jan 28, 9, Nov 13, datasheett. Would one of these work for now? Can we use a tristate buffer in place of voltage level shifter? I am trying to fix my Tek scope power -8 and power supply. Nov 13, If the opamp is in a socket, why not try testing it on the bench? Quote of the day.

I suspect that the op amp in the circuit is bad. Nov 13, 2. Can I use a pen or mechanical pencil Posted by coonsaa0 in forum: 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. That can be remedied. Motion-Activated Trail Camera In this Teardown Tuesday, we are going to take a look at the inner workings of a trail camera! What voltage do you measure across capactors C and C?

Bottom line, compare the datasheets of the op amps for compatability. Oct 29, 7, 3, Can I use a flyback transformer in a forward topology? Nov 13, 9. Apr 5, 18, 3, Nov 13, 8.

Posted by spidermanIIII in forum: The voltage you measured across C was around 15 volts. First off datashwet was probably not necessary to start a new thread since members are going to datashwet a bit confused between the two.


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. 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.

A Non-Invasive Glucose Sensor Researchers believe that sweaty armpits may be the answer to both detecting and datzsheet diabetes. Can U use 2 transistors in place of a relay to switch 2 different voltages Posted by icadj in forum: Your cc1458c or email address: 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.

You might find that one or more of the transistors connected to the output is shorted. It is a CC.
