Our class-D car radio audio amplifiers combine high reliability with genuine affordability, and add meaningful features that improve performance. A complete range is available from 26 W up to 130 W

Key benefits

• High voltage technology reduces diameter and weight of cables
• Audiophile sound quality
• Lowest power consumption
• Pin-to-pin compatible families
• Low PPM-rates, enhanced robustness

Key features

• Advanced protections prevent audio-holes and pop noise
• Audio amplifiers with analogue inputs and (digital-inputs)
• Closed loop topology supports low-cost (weak) power supplies
• Packages available that enable single layer PCB designs for head units and sound systems
• Automotive qualified AEC–Q100

Key applications

• Car radio head units
• Sound system trunk units

Descriptive summary

Using a practically inaudible automatic power reduction scheme, our class-D car radio amplifiers avoid over-temperature conditions and, as a result, have no audio holes under every condition. Pin-to-pin compatibility within each family means you get the most practical solutions, while low-cost, single-layer PCB reference designs ensure optimal performance for EMC.
