11.1 Device Support

11.1.1 Development Support

11.1.1.1 TINA-TI™ SImulation Software (Free Download)

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

simulation software is a free, fully-functional version of the TINA software, preloaded with a library of macro

models in addition to a range of both passive and active models. TINA-TI simulation softwate 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 simulation software offers extensive

post-processing capability that allows users to format results in a variety of ways. Virtual instruments offer

the ability to select input waveforms and probe circuit nodes, voltages, and waveforms, creating a dynamic

quick-start tool.

Note

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.

11.1.1.2 WEBENCH Filter Designer Tool

WEBENCH® Filter Designer is a simple, powerful, and easy-to-use active filter design program. The WEBENCH

Filter Designer lets you create optimized filter designs using a selection of TI operational amplifiers and passive

components from TI's vendor partners.

11.1.1.3 TI Precision Designs

TI Precision Designs are available online at http://www.ti.com/ww/en/analog/precision-designs/. TI Precision

Designs are analog solutions created by TI’s precision analog applications experts and offer the theory of

operation, component selection, simulation, complete PCB schematic and layout, bill of materials, and measured

performance of many useful circuits.
