I am in need of te LTSpice symbol for the TLV9062SIRUGR TI part. I can't seem to find it on this site and any help would be greatly appreciated.
You won't find LTspice symbols for random components (especially semiconductors) made by competing manufacturers. Therefore, you have two other choices:
- Adapt one of LTspice's.
- Make your own.
What kind of part is this? Let's start with the part number. What is its base part number? Most part numbers have suffixes added, and you can typically ignore them most of the time. Would it be correct to call it a TLV9062?
Regardless, the question is, what is that part? It appears to be a (dual) op-amp. Ignore the fact that it is a dual, because it never matters for SPICE. SPICE models are for a single part, and you just use two of them on your schematic to make a dual.
LTspice has an op-amp symbol, which is perfect for the majority of op-amps in the world. Its name is "OPAMP2". Open your schematic, open the part selector, type "OPAMP2", and add one to your schematic. Make sure to use opamp2 and not opamp, and not UniversalOpamp2 or anything with a similar name. Only the opamp2 is the right one. It has two inputs, one output, and + and - power pins.
Change the name "opamp2" next to the symbol to match the name of your SPICE model.
There is one other caveat: The pin-order must be correct. The opamp2 symbol requires that they be in this order: In+ In- V+ V- Out. Almost all op-amp SPICE models are in that order, but a few are not.
Making your own symbol is not that hard. There is even a shortcut, described in LTspice's Help for "Third-Party Models". However, use that only as a last resort when nothing else works. You'd get a plain rectangle that looks nothing like an op-amp, and now you need to use your custom symbol, which makes it harder to share your schematics with anyone else.
