National Semi announces WEBENCH active filter designer

National Semiconductor Corp. has announced its WEBENCH active filter designer, an online design tool aimed to speed the creation of filters for data acquisition and signal conditioning applications. The tool is anticipated to let engineers design advanced, highly customized filters for all standard filter types: low pass, high pass, band pass and band stop.

The WEBENCH uses a powerful component selection tool, developed by National Semiconductor engineers to rapidly search among the company's portfolio of operational amplifier products (each with hundreds of different electrical parameters) and immediately configure the necessary bill of materials for every design.

Performance curves for each of the recommended filters are calculated and presented. The filter designer then guides the user through the selected filter implementation, including selection of the best op amp to be used in the design, and selection of each filter stage's topology, including Sallen-key, multiple feedback and state variable types.

"Today, designers may use the WEBENCH active filter designer to develop more than 200,0000 customized low-pass filters using any of 180 op amps, including our brand new precision offerings," said Erroll Dietz, VP of National Semiconductor's amplifier product group.

To view a demonstration showing how to create a 9th order low-pass filter with Bessel response in 30 seconds, see http://filterdemo.national.com.
