Re: Pending acquisition of LTC by ADI
¿ªÔÆÌåÓýNot likely, right now LTspice models
for many LT parts are not available since LTspice tends to cater
to their department mostly.

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... AG |

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! On 27 Jul 2016 23:07, "helmutsennewald@... [LTspice]" <LTspice@...> wrote:

Re: Analog Devices to buy LT!
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. ? Best regards, Helmut PS: I am not an employee of Linear Technology. All my postings are my private statements.? |

Re: INA282
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. Use the "Table of Contents" file (all_files.htm) to search for files from this group's archives.? The group has 100MB of files, which are kept for a reason. Andy ? |

Re: Cap param with parasitic elements
enricosilv?wrote: ? ?"How can i write a directive like:?.param Cx 6.8n Rser=1 Lser=10n? ? ? And in the circuit name a capacitor with {Cx}" 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. Regards, Andy |

Re: INA282
Finally, you (riscy00) uploaded a file to the Temp folder. But there is still no schematic! This means we STILL do not know what you were trying to simulate, what the circuit was that had the problem. We cannot diagnose a problem when you don't show it to us.? That's like asking a doctor to fix you, but not letting the doctor examine you to see what is wrong. Andy ? |

Re: INA282
riscy00 wrote: ? ?"I have put these file into folder I assumed it visable to you, it seem not the case so I put the folder as designated." You have not. So far, you have not uploaded any file to the Temp folder. So far, you have not uploaded a schematic. A schematic is a file ending in .ASC.? You uploaded a model file, and three symbol files, but no schematic.? Without the schematic, we have NO IDEA what you were trying to simulate -- what the circuit was that used the INA282. Andy |
