Re: low noise amplifier
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

Re: Changing an opamp type in one circuit changes output in another isolated circuit
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,

Help! How do I do find maximum signal easily!
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

Changing an opamp type in one circuit changes output in another isolated circuit
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

Re: A TVS does not work with load dump test??
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

Re: A TVS does not work with load dump test??
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

Re: A TVS does not work with load dump test??
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

Re: Determining the value of a variable at time t-1
LTspice DOES NOT generate values at uniform sample times. So, "previous sample" (in the context of LTspice computation) makes little sense. If you do want to evaluate in terms of a sampled data

Re: A TVS does not work with load dump test??
Hi eqmqiq Ohms law says that your current is over 20A Quite a lot for a little TVS. Theyre usually meant for short spikes. 20A * 36V = 720W That would convert youre TVS into a SED in short order.
