CC(IC) NTE Equivalent NTEA dual operational amp – Wholesale Electronics

As the -8volts drops the positive input to the opamp begins to go positive. 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. No, create an account now.

What voltage do you measure across capactors C and C? Posted by Gamedojo in forum: Discussion in ‘ General Electronics Chat ‘ started by spinnakerNov 13, It is a CC.

Jul 17, 22, 1, You might find that one or more of the transistors connected to the output is shorted. As for the power supply, the opamp is actually being operated dataaheet an opamp rather than a comparator. 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. Nov 13, 4.

Can U use 2 transistors in place of a relay to switch 2 different voltages Posted by icadj in forum: Just so that I am clear. Jan 28, 9, Would one of these work for now? Nov 13, 6.

First off it was probably not necessary to start a new thread since members are going to be a bit confused between the two. Yes, my password is: I would have to know the part number to answer your question with certainty.

This results in a restoration of the -8volt output so that the droop due to the increased load is cancelled. Can I use a pen or mechanical pencil Posted by coonsaa0 in forum: I went out a purchased a couple of op amps from Radio Shack and built a comparator like the first one on this page. Your name or email address: I could probably ramp the voltages up to 15 VDC if that is recommended.

Apr 5, 18, 3, Posted by spidermanIIII in forum: If the opamp is in a socket, why not try testing it on the bench? Nov 16, 1, The voltage you measured across C was around 15 volts. Nov 13, 7. 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.


Could this finally be the dawn of room-temperature superconductors? Is this a good enough test for U A and B in t his schematic? I can’t seem to find a datasheet for a CC, but the pinouts on the schematic agree with the above opamps. You placed your DVM probes on the negative and positive terminals of the capacitor and the voltages you posted are the ones you read.

Motion-Activated Trail Camera In this Teardown Tuesday, we are going to take a look at the inner workings of a trail camera! I really do not care if one of these is the best choice. In the meantime, I will use the values you have measured. Do you already have an account?

c1458 I am trying to fix my Tek scope power -8 and power supply. But would want to run ti by the folks here anyway. Quote of the day. Nov 13, Here are my voltage readings for the -8 section. I have it working. Nov 13, 5. That can be remedied.
