November 2012
FAB2210 Audio Subsystem with Class-G Headphone and
3.3 W Mono Class-D Speaker with Dynamic Range Compression
Features
Description
The FAB2210 combines a Class-G stereo capacitor-
High-Efficiency Stereo Class-G Headphone
free headphone amplifier with a mono Class-D
- 100 dB SNR Headphone Amplifier
speaker amplifier into one IC package.
- Capacitor-Free Outputs for High-Frequency
Response
The headphone and speaker amplifiers incorporate
Class-G and Class-D topologies, respectively, for low
Mono Filterless Class-D Speaker Amplifier
power dissipation, which extends battery runtime.
- 91% Efficiency for Extended Battery Runtime
- DRC for Louder SPL and Speaker Protection
The Class-G headphone amplifier incorporates an
- 3.3 W into 4 at 5.0 V, THD+N < 10%
integrated charge pump that generates a negative
- 1.27 W into 8 at 4.2 V, THD+N < 10%
supply rail for ground-centered headphone outputs.
- Low EMI Edge-Rate Controlled output
The Class-D amplifier includes programmable
- 97 dB Signal-to-Noise Ratio (SNR)
Dynamic Range Compression (DRC) that maximizes
Click and Pop Suppression
Sound Pressure Level (SPL) for maximum loudness,
while protecting the speaker from damage.
Selectable Single-Ended or Differential Audio
Inputs for High Common-Mode Rejection
The noise gate can automatically mute the speaker or
