Block diagram

Overview

When driver audio expectations exceed the capabilities of the standard vehicle entertainment system, a boosted audio amplifier with active noise cancellation (ANC) enables a premium audio experience that meets the highest performance standards. Our integrated circuits, reference designs and products enable you to efficiently design systems and decrease development time.

Design requirements

  • Improved sound quality by reducing audible noise and distortion.
  • High power and performance in small spaces.
  • Advanced power stage control for optimized amplifier efficiency and improved thermals.
  • Processors running sophisticated signal processing algorithms that allow maximized performance for each vehicle and a quieter cabin.
