FAB3103 Datasheet (Fairchild Semiconductor) - 2.3 Watt Class-D Audio Amplifier

FAB3103, 2.3 Watt Class-D Audio Amplifier

The FAB3103 is a mono Class-D audio amplifier with an integrated boost regulator that achieves high output audio over a power supply range of 2.5V to 5.2V.

Automatic Boost Shutdown dynamically shuts down the boost regulator at low output power for greater efficiency and lower quiescent current consu
