I can not access the File directry of LTspice
Hi Everyone! I have already get the information that LTspice system was hacked. I can not access the File directory of LTspice. Because the Yahoo ask me *3 steps* to join the LTspice. But I can not

Re: kevin, check your spam folder - my emails to you might have gone there
Good morning, I'm glat to participate in yahoo groupe. I have a problem for looking for librery of Multiplxer DG406 I had used the LTspice, and I found ADG406, but the GND for this integret cicuit is

Re: THD-prob (bug) demo is here
Ok. Thanks. Works now. The THD calculation needs to be run with the name that shows in the plot when you probe that point in the fourier directive. I think I did have an alias for OUT before that was

Flback converter instability
Hi, I am facing issues with the flyback stability. The flyback is the +28V to +5V converter. The +5V is inturn used to convert another supply to +3.3V and +3.4V(two seperate converters using LTC 1778)

Re: LT1210 has two + inputs?
Hello, Yes, the lower + terminal should be marked -. The models "test circuit" show a negative supply connected to that pin. Rick
