The latest Webench Signal-Path Designer toolset from National Semiconductor gives engineers an easy-to-use tool to select, design, and evaluate critical data converter and amplifier/filter components and circuits. Designing signal paths is a known art form where analog experts select resolution, sampling speed and filtering required by their desired system performance. The effects of noise, impedance, signal-level matching and power usage all play a significant role.
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 the optimal performance ADC/amplifier circuit. The tool also provides filter simulations for both the ideal and device models for comparison purposes. To see the tool quickly create an optimized 12-bit, 1 Msample/s signal path, visit webench.national.com/signalpathdemo.
