TFA9894: Highly power-efficient DSP embedded class-D audio amplifier
Audio amplifier solution associated with speaker protection and boost algorithm
Several trends shape today’s audio reproduction needs—more channels per unit, more integrated sound processing features, and the continual drive toward increased efficiency. These trends affect the choice of amplifier and how the circuit is designed.
In response, NXP's portfolio of audio amplification technologies enables the latest portable equipment and audio component designs. This includes miniaturized devices that maximize the effect of small form factor speakers to generate a big, high-quality sound. Our audio amplifier solutions provide excellent EMC performance (especially in noisy environments) to ensure distortion-free listening.
