11.1 Device Support

11.1.1 Development Support 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 macromodels 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, thus creating a dynamic quick-start tool.


These files require that either the TINA software (from DesignSoft™) or the TINA-TI™ software be installed. Download the free TINA-TI™ software from the TINA-TI™ folder. DIP Adapter EVM

The DIP Adapter EVM tool provides an easy, low-cost way to prototype small surface-mount devices. The evaluation tool these TI packages: D or U (SOIC-8), PW (TSSOP-8), DGK (VSSOP-8), DBV (SOT23-6, SOT23-5, and SOT23-3), DCK (SC70-6 and SC70-5), and DRL (SOT563-6). The DIP adapter EVM can also be used with terminal strips or can be wired directly to existing circuits. Universal Op Amp EVM

The Universal Op Amp EVM is a series of general-purpose, blank circuit boards that simplify prototyping circuits for a variety of device package types. The evaluation module board design allows many different circuits to be constructed easily and quickly. Five models are offered, with each model intended for a specific package type. PDIP, SOIC, MSOP, TSSOP, and SOT23 packages are all supported.


These boards are unpopulated, so users must provide their own devices. TI recommends requesting several op amp device samples when ordering the Universal Op Amp EVM. TI 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, a complete PCB schematic and layout, bill of materials, and measured performance of many useful circuits. TI precision designs are available online at WEBENCH® Filter Designer

The WEBENCH® Filter Designer is a simple, powerful, and easy-to-use active filter design program. The WEBENCH® filter designer enables optimized filter designs to be created by 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, the WEBENCH® filter designer allows complete multistage active filter solutions to be designed, optimized, and simulated within minutes.
