A Signal-Path Designer toolset for WEBENCH from National Semiconductor is aible to select, design and evaluate critical data converter and amplifier/filter components and circuits. To see the tool create an optimized 12-bit, 1 mega-sample per second (MSPS) signal path in two minutes, visit http://webench.national.com/signalpathdemo.

The Signal-Path Designer tool offers an intuitive, step-by-step guide to balance the resolution, speed and power consumption of a performance-matched ADC with the ideal filters, passive components and amplifier to create a ADC/amplifier circuit.  The tool also provides filter simulations for both the ideal and device models for comparison purposes. 

The tools offer instant access to SPICE models, parametric data and package information, enabling designers to simultaneously compare the performance of multiple devices in multiple circuit requirements. The WEBENCH Signal-Path Designer toolset works seamlessly with National’s other WEBENCH tools for power, audio, amplifiers and active filters, including http://Solutions.National.com and National’s online distance learning facility, Analog University.
