General Description

The TFA9887 is an audio system consisting of a high efficiency class-D audio amplifier, and embedded DSP with a sophisticated speaker-boost and protection algorithm and an intelligent DC-to-DC converter.

It can safely deliver 2.65 W (RMS;

THD = 1 %) output power into a 4  speaker that is nominally only rated for 0.5 W.

Overview

TFA9887 Audio system with adaptive sound maximizer and speaker protection Rev.

1 — 11 July 2012 Product short data sheet 1.

Key Features

Sophisticated speaker-boost and protection algorithm that maximizes speaker performance while protecting the speaker:.
Fully embedded software, no additional license fee or porting required.
Total integrated solution that includes DSP, amplifier, DC-to-DC, sensing and more.
Adaptive excursion control - guarantees that the speaker membrane excursion never exceeds its rated limit.
Real-time temperature protection - direct measurement ensures that voice coil temperature.
