SBOS445C July 2008 – December 2015 INA333
Using TINA-TI SPICE-Based Analog Simulation Program with the INA333
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 both passive and active models. It provides all the conventional DC, transient, and frequency domain analysis of SPICE as well as additional design capabilities.
Available as a free download from the Analog eLab 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 41 and Figure 42 show example TINA-TI circuits for the INA333 device that can be used to develop, modify, and assess the circuit design for specific applications. Links to download these simulation files are given below.
These files require that either the TINA software (from DesignSoft) or TINA-TI software be installed. Download the free TINA-TI software from the TINA-TI folder.
