Zulumuro Posted by dagasheet in forum: Nov 13, 2. Would one of these work for now? I could probably ramp the voltages up to 15 VDC if that is recommended. The voltage you measured across C was around 15 volts. Nov 13, 5. 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: I have it working. Nov 13, 1. Is this a good enough test for U A and B in t his schematic? I am not great at reading datasheets. Nov 13, 4.
The trick to the -8volt regulator stage is that Q is acting to control adtasheet positive-most end of the 15V secondary transformer winding so that it is exactly 7 volts positive when measured with respect to ground.
I really do not care if one of these is the best choice. I have included the PS schematic below. I am trying to fix my Tek scope power -8 and power supply. Nov 13, catasheet. Jul 17, 22, 1, Apr 5, 18, 3, Your name or email address: Motion-Activated Trail Camera In this Teardown Tuesday, we are going to take a look at the inner workings of a trail camera! Nov 16, 1, Would one of datashete work for now? That can be remedied. 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. This will help prevent confusion since replying members will be less likely to be confused. Actually the voltage measurement I would like you to make is the voltage across the terminals of the capacitor. I could probably ramp the voltages up to 15 VDC if that is recommended. This results in a restoration of the -8volt output so that the droop due to the increased load is cancelled. I would have to know the part number to answer your question with certainty.
But would want to run ti by the folks here anyway. Jan 28, 9, The voltage you measured across C was around 15 volts. With an increase in the base drive applied to Q, it begins to turn on harder. Bottom line, compare the datasheets of the op datashheet for compatability. I started reviewing the lessons on datssheet amps on this site because I think the problem with my Tek scope power supply is a bad op amp. Nov 13, 6.

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.
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. PDF CC Datasheet download 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. 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. What dahasheet do you measure across capactors C and C?
Nov 13, 6. Nov 16, 1, Nov 13, 3. Nov 13, 1. I started reviewing the lessons on op amps on this site because I think datsheet problem with my Tek scope power supply is a bad op amp.
