The "Pick New Transistor" function is wonderful, allowing me to sort by key features for an easy selection of the available library of parts. Is there any way to access a selector menu like this for the wide selection of LT opamps? I really want to use LT opamps in my current design, but I'm getting tired of going up to the LT site and using their feature selection tool to find an appropriate opamp. If I think I need an amplifier with a faster slew rate to solve my immediate problem, it would be nice to get into the LTspice opamp selection menu, sort by slew rate, then select a device that has the proper range of features. I often find myself running simulations in places where I don't have access to the LT website, so this feature would be really nice to have. Is it already there and I just don't know about it?

Hello Carl,

I'm not sure whether this would rate as equivalent to the "Pick New Transistor" dialogue, but if you open the parts chooser and browse to the Opamps sub-section, you will find pretty much all of LT's opamps there. If you step through the list, most of them have a potted description of what they are and what they do, alongside the preview of the symbol.

Would this do for you, or were you thinking of something else?

Regards,
Tony

Maybe a kind of parametric search as provided on distributors pages?
Selecting a range on different parameters?

I think LTspice is a program for simulation. Not for selecting parts for your hardware-schematic.

Yes, it's nice that LTspice provides you the most common parameters for transistors. But choosing the appropriate parts for your hardware is another job.

Hello Heinz-W (what does the W stand for?),

I don't always completely agree with you, but this time I do.

For situations when you don't quite know the specification of the device you require for a given application, the behavioural devices are exactly what you need: like opamp2 or uninversalopamp2 (there is also an enhanced version, unsurprisingly called univeralopamp3, that never made it into general release). You can find for yourself which parameter actually limits a particular application.

For other types of device, it is even easier because there is direct access to the parameters of intrinsic devices, like BF, VAF, etc for bipolar transistors. There are many examples from Helmut of how to modify these and other devices for what-if? situations.

Regards,
Tony

Maybe I'm just a little bit lazy, since there are over 300 amplifiers to chose from in the LT selection window. Yes, they do have a one-line overview of the good specs, but being able to sort (like on the website selector page) is what I was hoping for.
Thanks to those who had other suggestions (universal opamp), but I wanted to "play with real opamps" before I ordered some samples for my breadboard.
