Hi Everybody,
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
Thanks
Cuong
Hi Cuong,
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.
Hi Chuong,
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.
