The FAB2210 combines a Class-G stereo capacitor-free headphone amplifier with a mono Class-D speaker amplifier into one IC package.The headphone and speaker amplifiers incorporate Class-G and Class-D topologies, respectively, for low power dissipation, which extends battery runtime.The Class-G headphone amplifier incorporates an integrated charge pump that generates a negative supply rail for ground-centered headphone outputs.The Class-D amplifier includes programmable Dynamic Range Compression (DRC) that maximizes Sound Pressure Level (SPL) for maximum loudness, while protecting the speaker from damage.The noise gate can automatically mute the speaker or headphone amplifiers to reduce noise when input signals are low.
