Op-amp design tool is highly flexible

The iSim v4.1 is an upgrade to the company’s web-based non-inverting and inverting op-amp design tools. These tools build on the previously released Active Filter Designer and expand the solution set offered by Intersil's interactive online tools.

Both tools efficiently select and simulate the optimum Intersil precision or high-speed op-amp device, resolving implementation issues that provide board ready solutions to the system designer. This approach is powered by online macro models that capture all critical second-order effects. With up to six possible input interface options, the tool matches requirements to the optimally suited device and generates a complete design with immediate simulation capability.

iSim also takes numerous second-order effects into consideration, including total output noise, input bias current, total output offset voltage, and slew rate limits. Once designed, the tools allow immediate simulation of small signal ac response, step response, and/or output noise. An immediate redesign feature is supported in each tool, giving the design the option to override the suggested component values. Additionally, schematics generated by this online tool can also be downloaded and run on the iSim:PE desktop simulator. (Free download — available now.)
