General-purpose audio amplifiers

Our smart amplifier technology uses real-time current (I) and voltage (V) sensing to actively monitor speaker conditions and prevent damage from excessive temperature or excursion. Closed-loop protection enables you to safely push speakers to their performance limits without affecting reliability.

By optimizing output in real time, IV sensing delivers louder, cleaner sound and helps you achieve premium audio performance in space- and cost-constrained automotive designs.

Our audio amplifiers include advanced technologies to maximize efficiency and reduce power losses. A Y-bridge intelligently switches between voltage rails based on power demand, lowering idle consumption by as much as 90% and improving efficiency 15% to 20%.

Class-H amplifiers work with an internal or external buck-boost converter to dynamically adjust the supply voltage using envelope tracking, providing only the power that the audio signal needs. These features help automotive and battery-powered audio systems run cooler, extend battery life, and maintain high-quality sound.

Reducing bill-of-materials (BOM) cost and board space is a priority for automotive and portable audio designers. Embedding important functions directly into our devices minimizes the need for external components while improving performance and reliability.

Our portfolio integrates high common-mode rejection ratio line receivers, boost converters with low-dropout regulators, successive approximation register analog-to-digital converters for input diagnostics, headphone amplifiers, digital signal processing (DSP) for advanced equalization and speaker protection, real-time load diagnostics, and class-H control for enhanced efficiency. This integration simplifies designs and accelerates time to market without compromising sound quality.
