Speaker Amplifiers

Speaker Amplifiers

Analog Devices’ speaker amplifier ICs combine superior sonic quality with technological breakthroughs, which simplify the design process, save space, extend battery life, and reduce system cost. Our speaker amp ICs offer output power levels from less than 1 W up to 50 W. ADI’s innovative packaging technology provides the smallest Class AB and Class D amplifiers available. Our IV sense boosted Class D speaker amplifiers employ our patented dynamic speaker management (DSM) technology, providing up to two times loudness improvement over standard Class D amps.

Boosted

Analog Devices boosted speaker amplifier ICs are designed for battery-operated portable devices. Integrated boost converters provide constant output power for louder audio output over a wide range of battery supply voltages.

Class AB

Class AB speaker amplifiers have higher efficiency than Class A, but less distortion than Class B. Analog Devices’ Class AB speaker amp ICs offer high SNR and low THD+N, while typically achieving up to 65% efficiency, making them ideal choices as high fidelity speaker drivers. They are used in applications such as portable media players, digital cameras, tablets, and eReaders where high fidelity is a necessity.

Class DG

Analog Devices’ Class DG speaker amps offer highly efficient, high power audio portable solutions. Class DG multilevel architecture combines Class D switching output efficiency and Class G supply level shifting to more efficiently supply the required signal power. This allows for optimal efficiency over a wide output range.

Class-D Audio Amplifiers

ADI’s industry-leading audio signal processors include Class-A, Class-B, and Class-D audio amplifiers that deliver high performance with proven analog and digital technology.
