Hi ppl, I thought I would search for it - to test my abilities - I didn't find it. I am learning a fair amount by just reading this group and others troubles. So as my first reply to the group I will

Hello, Thanks for this report. The power pin at the bottom should have a "-". I have reported now this bug to Mike. Please directly report this to LTC in the future, if you find a bug. The email

I've been using TI's TL081 model without any problems but created my own symbol, just copied something else and renamed it. Gordon --

Hello, Yes, the lower + terminal should be marked -. The models "test circuit" show a negative supply connected to that pin. Rick

Hello, I wonder what you did. My colleagues and I permanently use models from LTC and other companies at the same time. They have no problems with that except that some models hardly converge, but

Is this an error? I just started using LTspice and I'm trying to use a circuit with an LT1210 and it shows two + supply inputs instead of the usual + and - supply inputs. Thanks gentlemen.

Hi Helmut, as always, I am deeply appreciative of this group, of your moderation and assistance, and to LT for making it free. having said all that, I have noticed one thing that I don't think is

Hi Tom. tomshong wrote: Just d/loaded your schematic. Edited Simulation command. Removed .op analysis Added transient to run for 1ms (first and only parameter). Pretty wave form. :-) Half a megahertz

I'm trying to figure out how to model a standard No. 47 flashlight lamp. I'm having trouble trying to find a similar model. Oh yeah, I'm new to this software.

1MHz IS in the AM band. 1MHz = 1000KHz. The AM band in the North America goes from 531KHz to 1881KHz, That puts 1MHz right in the middle. In some parts of the world, this is referred to as the "MW"

Will get the latest version and recheck. I was using 4.15r. Thanks. Helmut wrote:

Thanks. I ran the simulation a few times times over the weekend, and I got more questions... 1) Why was the carrier signal set as 1 megahertz? That's not in the AM band. 2) Looking at the Transient

The .four or .fourier spice directive using the syntax in the docs does not appear to work correctly. When I create a net label named "OUT" and set the directive like so: ".fourier 1k v(out)" ltspice
