TFA9887UK: 3.7 W audio system with adaptive sound maximizer and speaker protection
Housed in a small, cost-efficient wafer-level chip-scale package, this complete audio system includes an embedded DSP (running advanced algorithms for speaker boost and protection), a high-efficiency 2.65 W Class-D audio amplifier, and an intelligent DC-to-DC converter.
- Louder sound: the maximum possible from small speakers
- Deeper bass: reproduces lower frequencies than traditional systems
- Better quality: unmatched sound clarity with less clipping in the amplifier and less distortion from the speaker
- Longer life: prevents speaker damage with adaptive excursion control and real-time temperature protection
