TINA-TI — The Complete Guide: The Free SPICE Simulator From Texas Instruments
TINA-TI is a free version of the TINA simulator that DesignSoft prepared for Texas Instruments. You draw a circuit, run analyses and probe nodes with virtual instruments — a handy way to check a circuit before ordering parts.

- Analyses — DC, transient and frequency response.
- Virtual instruments — measurements at circuit nodes.
- Post-processing — extensive tools for processing and plotting results.
- TI models — Texas Instruments analogue and power parts.
- External models — loads additional SPICE models.
Who may use it for free
TINA-TI is free for professional design work, and TI charges nothing for it. Before downloading you certify that it will not be used by teachers, students or anyone for educational purposes, and you accept a US export-control declaration. It also lacks some capabilities of the full TINA. Students and lecturers need to choose a different simulator.

TINA-TI is a good tool for an engineer designing with TI parts. In the classroom or a course, the download terms forbid using it.
