11.1 Device Support

11.1.1 TINA-TI (Free Download Software)

TINA is a simple, powerful, and easy-to-use circuit simulation program based on a SPICE engine. TINA-TI is a

free, fully functional version of the TINA software, preloaded with a library of macromodels in addition to a range

of passive and active models. It provides all the conventional dc, transient, and frequency domain analysis of

SPICE and additional design capabilities.

Available as a free download from the WEBENCH® Design Center, TINA-TI offers extensive post-processing

capability that allows users to format results in a variety of ways.

Virtual instruments offer users the ability to select input waveforms and probe circuit nodes, voltages, and

waveforms, creating a dynamic quick-start tool.

Figure 15 and Figure 16 show example TINA-TI circuits for the TMP20 that can develop, modify, and assess the

circuit design for specific applications. Links to download these simulation files are given below.

NOTE

These files require that the TINA software (from DesignSoft) or TINA-TI software be

installed. Download the free TINA-TI software from the TINA-TI folder.

Note:

The TMP20 TINA model is preliminary only.
