TFA9888

9.7 V stereo boosted audio system with adaptive sound

maximizer and speaker protection

Rev. 1 — 29 February 2016

Product short data sheet

1. General description

The TFA9888 is a high-efficiency stereo class-D audio amplifier featuring an adaptive

sound maximizer and speaker protection (implemented via a speaker-boost and

protection algorithm). It can deliver 4.8 W peak output power per channel into an 8 

speaker at a supply voltage of 3.6 V. The internal adaptive DC-to-DC converter raises the

supply voltage to 9.7 V, providing ample headroom for major improvements in sound

quality.

A safe working environment is provided for the speaker under all operating conditions.

The TFA9888 maximizes acoustic output while ensuring diaphragm displacement and

voice coil temperature do not exceed their rated limits. This function is based on a

speaker box model that operates in all loudspeaker environments (e.g. free air, closed box

or vented box). Furthermore, advanced signal processing ensures that the quality of the

audio signal is never degraded by unwanted clipping or distortion in the amplifier or

speaker. The speaker-boost and protection algorithm uses feedback to calculate both the

temperature and the excursion, allowing the TFA9888 to adapt to changes in the acoustic

environment.

The device allows a single speaker to support both the handset call and handsfree call

use-cases. This feature reduces the number of amplifiers needed in an application without

the need for additional external components.

Smart Receiver stereo playback is supported with a handsfree speaker and an earpiece

speaker (32 ) connected to the two channels of the TFA9888. The speaker-boost and

protection algorithm allows the TFA9888 to deliver about 1.2 W at the earpiece speaker,

making it possible to generate a loud stereo impression using normal mobile phone

acoustics.

The TFA9888 is available in a 99-bump WLCSP (Wafer Level Chip-Size Package) with a

400 m pitch.

2. Features and benefits

 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 Digital Signal Processor (DSP), stereo

amplifiers, DC-to-DC converter sensing and more

 Adaptive excursion control - guarantees that the speaker membrane excursion never

exceeds its rated limit
