ACTIVE

Description

Calculate and design audio Class-D LC filters in minutes using the Class-D LC Filter Designer.  Select from 4 different filter types based on Class-D output, switching topology and performance.  Input corner frequency and quality (Q) factor to fine tune the audio frequency response.  Finally, verify the selected LC components with multiple speaker loads using the frequency response graph and Q-factor calculations.  The Class-D LC Filter Designer is the perfect quick and easy tool to get started on your next Class-D audio design!

Features
  • Calculate LC filter inductor and capacitor values quickly
  • Select from 4 different Class-D filter types
  • Tune frequency response with corner frequency and quality factor (Q) inputs
  • Verify and graph filter response with multiple speaker loads
