High-efficiency audio signal-processing and power-amplification solutions for smart speakers, soundbars, televisions, professional audio equipment and connected entertainment systems.
Digital audio processing and efficient power delivery for high-performance speaker systems
Modern audio systems require a clean digital signal path, precise real-time processing and an efficient output stage capable of driving demanding loudspeaker loads. The DSP controller performs equalization, crossover, dynamic-range control, protection and system coordination, while the power amplifier converts the processed signal into high-current speaker power with low distortion and controlled thermal performance. This architecture supports scalable mono, stereo and multi-channel designs across compact consumer products and higher-power professional equipment.

About the solution
Coordinated DSP processing and efficient speaker-power conversion
The audio input and codec stage provides digital or analog source conversion, after which the DSP controller performs equalization, crossover, delay, dynamic-range control and system protection. The power amplifier then converts the processed waveform into the voltage and current required by the loudspeaker. Output-current, temperature, clipping and fault feedback allow the controller to protect the speaker and amplifier while maintaining consistent acoustic performance.
Scalable for smart speakers, soundbars, televisions and professional audio equipment
The architecture can be configured for mono, stereo or multi-channel products, with power levels ranging from compact connected speakers to higher-output entertainment and professional systems. Designers can adapt channel count, crossover strategy, protection limits and power-stage sizing without changing the fundamental signal-processing and amplification workflow.
Audio processing, power switching, gate driving, sensing and protection components
DSP and control devices, audio interfaces, low-loss MOSFETs, half-bridge gate drivers, current-sense amplifiers, power-management ICs, protection devices and memory components form a practical semiconductor platform for efficient, reliable and production-ready audio amplifier designs.
