Design of High-Performance Balanced Audio Interfaces - Part 6
Design How-To  
1/14/2007   Post a comment
Balanced inputs benefit from specialized circuitry. The InGenius circuit silicon implementation differs from the discrete solution in many respects. Since all critical components are integrated, a well controlled interaction between resistor values and metal traces can be duplicated with similar performance from die to die. But the integration of certain components creates new challenges.
