Amplifier Filter Design Software

August 1, 2010

Texas Instruments (Dallas, TX) has introduced the FilterProTM v3.0 design tool with an improved user interface and a more accurate and robust filter design engine. It can adjust passive element tolerances and view response variations, scale passive component values, and view and export filter performance data to Excel. The tool allows designers to create and edit designs using the Filter Design Wizard. Users can design multiple feedback (MFB), Sallen-Key, low-pass, high-pass, band-pass, and bandstop filters using voltage feedback op amps. The software supports Bessell, Butterworth, Chebychev, Gaussian, and linear phase filter response types, and can be used to design filters from one to ten poles.
