FilterLab Circuit Schematic
The Circuit Schematic tab contains the schematic of the filter. It also includes commands to download an image of the filter’s schematic, the bill of materials of the filter, and the SPICE code. The user can also quickly change the op amps being used in the filter.
Download Schematic PNG
This command downloads an image of the filter in PNG format.
Download BOM CSV
This command downloads a simple bill of materials of the filter in CSV format.
Change Op Amp
This command will navigate the user to Modify Current Filter > General > Filter Components. Enable Choose My Own Op Amp to allow the user to choose a particular op amp to use in the filter.
Choosing a particular op amp in the General section will change the op amp for all stages in the filter while changing the op amp in the individual stage section will only change the op amp for that one stage.
Download Spice Code
This command will export the macro model of the op amps used in the filter and the SPICE file of the filter circuit. Be sure to enable downloading of multiple files in your web browser to get all the necessary files.
