FAB1200 stereo Class-G ground-referenced headphone amplifier with integrated buck converter

The FAB1200 eliminates the need for two external capacitors and integrates an inductive buck regulator, resulting in reduced power consumption, lower system cost and extended battery runtime.

FAB2200 audio subsystem with stereo Class-G headphone amplifier and 1.2W Class-D mono speaker amplifier

The FAB2200 integrates a proprietary charge pump which reduces power dissipation, while offering high power supply rejection ratio. This amplifier can also be connected directly to a speaker without the need for two external filter networks, reducing the overall solution systems cost.
