Find Designs, Fast

About Reference Design Library

Instead of searching many manufacturer sites or calling on companies to find and compare designs, now you can search for designs based on the circuit’s performance using Digi-Key’s Reference Design Library.

The Reference Design Library was created in order to:

  • Save Engineers time
  • Deliver ideas, fast
  • Sift through designs based on performance
  • Provide designs conveniently accompanied by their schematics

Visit often as new designs are being added weekly and improvements will be made based on your constructive feedback.
