Hello Hamed, I had a chance to look at this a bit more closely, and I do think LTspice is having a problem with this circuit that it should not have. I have created a simpler version of your circuit,

It might be worth checking sparkfun.com for information on this link. I have read that they use eagle for production, and make available most (if not all) of there schematics and symbols. Also, since

Maybe not. But a complicated one. I, for one, have trouble understanding what exactly you are asking. Sorry. Andy

I can't believe no one has responded! Was this a stupid question? --- macy@... wrote: From: Macy <macy@...> To: <LTspice@...> Subject: [LTspice] Help! How do I do find

Hi, I don't know what your specific requirements are, but have you taken a look at the "AT-42086", made by Agilent (HP), it may meet your requirements. I have over 18,000 (18K) of these things on tape

I am inquiring about power transistor models... the devices are: 2n5591 or 2n6083 thank you.....Frank

I am looking for power transistor models for the following devices: 2N6083 or 2N5591 thank you for your help... Frank

Hi Helmut, Thanks again. I'll take another look at it and see if this time the penny drops :-) Greetings, Jesper

Hello Ross, unfortunately neither by Analog Devices nor in the internet is a .subckt ADCMP566 to find. :-( Leo

Hi does anyone have a model for the ADCMP566 comparator regards Ross

Hi Ferdian Cahyodwiputro. You gave yourself the problem from scratch. Using the command ". Inc" or ". Lib" you have to enter into it full name. In my electronic circuit: .inc 2SC5006.txt. If you like

Hi Mr.Александр Бордодынов i was download your file but cannot open in LTspice because format not .lib. can you upload again with format .lib for component transistor 2SC5006?

I think what's happening here is that your circuit has two possible stable states, due to the fact that it has no real V+ supply voltage. If the op-amp happens to start up yanking on the output pin,

I'm trying to find an easy way to see if my signal saturates any OpAmp output, or violates some level to the next stage. Right now, I'm using input values predetermined from matching to the existing

I have a circuit that uses an LT1702. To test some variations, I cloned that circuit so there are currently a pair of identical isolated circuits, both giving the same results (10.4V on the outputs of

Hmm, I missed that, even though it was there in the Subject. I was thinking that small stuff like ignition noise was all the suppressor diode had to handle. My bad. :-) Andy

Load dump can last for a long time. TVS is NOT generally used for load dump protection, just because of that. Instead, the emphasis is on using components (capacitors and voltage regulators) that will

Hi Andy Hmmm, load dumps can last a looong time. The large inductance field has to decay before the alternator stops producing the over voltage. 100s of mS, long enough to fry the TVS? Sorry for
