11.1.1.1 TINA-TI™ (Free Software Download)
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 macro models in addition to a range
of both passive and active models. TINA-TI 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 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 TI Precision Designs
TI Precision Designs, available online at http://www.ti.com/ww/en/analog/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.
11.1.1.3 WEBENCH® Filter Designer
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.
Available as a web based tool from the WEBENCH® Design Center, WEBENCH® Filter Designer allows you to
design, optimize, and simulate complete multistage active filter solutions within minutes.
