Save space and reduce costs without compromising automotive audio quality
Our one-inductor (1L) modulation is a proprietary automotive innovation that reduces the inductor count in inductor-capacitor filters by 50%, lowering cost, saving printed circuit board space, and minimizing system weight. Eliminating switching on one half bridge per channel reduces losses and increases efficiency by as much as 7% compared to traditional class-D modulation.
This technology integrates easily into class-D amplifiers without adding design complexity, while maintaining high-quality automotive audio performance. The TAS67xx family incorporates 1L modulation.
