I'm a newbie of TINA-TI software. I want to test INA333, but I alway have problem: "Wire is not connect" at pin Vin-, when I run ERC in Analysis menu.
Please help me to solve this problem
Welcome to the e2e Forum! Are you using the INA333 TINA-TI model found on the product page for the INA333 or did you wire up your own circuit? The implication of the error message is that pin 2 (the Vin(-) pin) is open. The TINA-TI example circuit works fine, so try using that as a starting point if you haven't already. You can find it here:
This error could also mean that you have a floating wire connected to that pin. Loacting and removnig the floating wire may get rid of this problem. If you can share your TSC file, we can have a look to confirm.

I had shared my file, but I do not sure you can read it.
In reply to Cuong Do:
As expected, it was a floating wire on the pin. For some reason, you had multiple wires on top of each other in several places in the design. I have cleaned it up. Please see attached. Note that the ERC check was only showing a floating wire "Warning" earlier (not an "Error"), so you could still run the simulation with it.
Let me know if you have any questions.
Hi Nikhil Gupta,
Thanks for your help,
Now problem is solved.
