Re: Analog Devices to buy LT!

 

How will this affect LTspice? These news come very soon after the XVII alpha, it sounds very strange for me. I hope things will not change for Mike's sector.

Agree. Mike is associated with the power management group and has no ¡°mandate¡± to deal with RF parts, for example (he told me this on his last World Tour). Would not surprise me if that continues. A change would be pleasant.

Interesting, thank for the info. It good to know it actually matured product, lesser risk.

Actually, the INA282 is not very new.? T.I.'s newest SPICE models for it are 5 years old.? The datasheet is newer, but was originally written in 2009, and the INA282 evaluation module user guide is 6 years old.

Re: NEW libraries LTspice

 

? ?"opam(p) NJM2903"

?That one is easily found on the web.? I found it here:



It's not really an op-amp.? It is a comparator.? Similar, but different.

I don't know how it differs from the LM2903.? There is an LM2903 model in the Temp -> on hold folder, here:

Re: Analog Devices to buy LT!

 

Greetings.
ADI has a good CAD org and I know most of those people,, They have 1 or 2 extremely talented algorithmic specialists.. Long term they will integrate Mike into that organization unless otherwise he chooses to be in his design role..
Based on their PMIi acquisition model, I can make the following predictions..
They will not disturb the design centers or the market and product space for LTC products.. However thee will be an effort at consolidating the wafer fab areas and roll them into their IRISH and other overseas fabs.. Both companies have a strong applications organization and it will be interesting ?to see how they converge.. Same goes for the sales force....
The 2 companies have a similar design culture but have a vastly different sales and applications focus.
Enough said...

Re: Analog Devices to buy LT!

 

That would be really great!!......now we wait do ti to aquire ltc and adi next to extend library more....that would be really great!

Hello,


I see no problem for the future of LTspice after this acquisition by Analog devices.
I read in the web that ADI is very interested on the power management ICs from LTC. I also see the advantage that all the SPICE models from ADI will be available/compatible for LTspice in the long run.

Watch the nice double-logo on this page.

Now it's clear what I can do, there are few solutions to my problem.

I thank All of you that have helped me.

Re: Cap param with parasitic elements

 

Dear theeten2, your propose does not make error, but Rser and Lser are ignored by LTspice


Re: INA282

 

Hello,

I haven't read all the previous postings. I just read that there has been already an example in the Lib-folder from 2012.?

INA282_test.zip

Re: INA282

 

Hello,

I just uploaded an example with the INA282 in the Temp-folder.

INA282_test.zip

?

I guess the simulation speed is slow, because of the internal switches running with 200kHz.?

Hi, Jim:

Thank you. I am trying.

But some info like "discharge" mechanism, not mentioned in the datasheet, I'm not sure if it's important or not.
It's a switch, dumping the timing ramp... download the AppNote:

<>

And the current feedback to control the PWM on&#92;off (through a comparator), datasheet said that there is a amplifier for the shunt res's current before doing this PWM comparator, that's not clear too.

As you said, it depends on the datasheet's content. (Vlad said it too.)

Best regards.
---------- End of Original Message ----------

And years of experience helps as well... I was just musing that I designed my first OpAmp (MC1530/31) some 53 years ago! And it's still being sold!

After all those years of IC design I tend to know exactly what's in a chip just from the datasheet/block diagram without ever seeing the schematic >:-}

Thank for your kind help (especially Andy), sorry to waste your time. I was suprised INA282 was included in the files considering it quite new part.

I think you can not use a parameter to replace the name of a capacitor -- not in the way you described.

However, there are many things you can do:

.param Cx=6.8n Rserx=1 Lserx=10n
Cy n001 n002 {Cx} Rser={Rserx} Lser={Lserx}

In the schematic editor, you can write your parameter names (in the boxes where the values normally go), by putting them within {curly braces}.

But it looks like you actually are better using a subcircuit!

.subckt Cx 1 2
C 1 2 6.8n Rser=1 Lser=10n
.ends Cx

and then in your main schematic/netlist:

XCx n001 n002 Cx

This .subckt...ends block defines a subcircuit element, named "Cx", which has the characteristics you defined.? Then that capacitor can be placed anywhere in your main circuit.

You can even use the capacitor symbol, by pressing Ctrl-right-click on the symbol and changing Prefix from C to X, and change Value to Cx.

Andy
