Diodes Incorporated features high-fidelity analog audio amplifiers that can deliver clean, efficient audio quality across a wide range of applications. From wearables to high-power consumer electronics, Diodes’ versatile portfolio of analog input Class-D amplifiers is diverse enough for all your design needs.
The PAMXX series of analog audio amplifiers combine high efficiency, low distortion, and flexible integration to reduce BOM and PCB size while delivering crystal clear sound. Whether you are designing for mono or stereo output, low or high-voltage operation, our amplifiers are engineered for efficiency and easy integration.
For power-hungry and battery-driven applications, our headphone amplifiers drive up to 100mW into 16Ω or 32Ω stereo at low quiescent current. Our stereo headphone drivers optimize board area with ease by eliminating the need for large output DC-blocking capacitors.
Diodes' analog input audio products include Analog Input Speaker Amplifiers, Haptic Drivers, and Headphone Amplifiers.
