NXP products are leading performers for sound, robustness and EMC performance. NXP invented the world’s first smart amplifier and shipping more than 400 million units per year of low power audio products.
Today’s audio technologies need to support portable equipment and audio component designs. While enabling miniaturized devices, they have to maximize the effect of small form factor speakers to generate a big, high quality sound.
Our Analog audio inputs class AB portfolio provides cost effective and protected solutions from 0.5 to 3.5 W with typical THD+N range of 0.15-0.3 % and wide supply voltage range of 2.2-18 V.
Class D is crucial to save battery life and meet the output power requirements with low dissipation. Our Class D audio amplifiers provide protected mono solutions from 2.35 to 3 W, delivering audiophile sound quality while maximizing audio system capabilities.
As speaker boost voltage requires precise speaker’s membrane excursion and coil temperature control based on speaker’s characteristics, related firmware tuning is necessary. This firmware adaptation is either managed in external host processor for Programmable smart amplifiers or in Smart audio amplifiers embedding a Digital Signal Processor.
NXP’s Smart audio amplifiers offer the most advanced solution to this conflict. They offer a turn-key solution for getting the most from micro-speakers. They offer the most advanced protection algorithm with the widest range of amplifier options ensuring the best sound from your mobile device.
