Overview

SC1105 is a class D audio power amplifier with single channel full bridge output. When the power supply voltage is 5V, 5W output power can be provided to 2 horn or 3W output power can be provided to 4 horn under the condition that THD is less than 10%. The peripheral components of the audio power amplifier are very few. SC1105 circuit features external control, low power switching mode and internal overheating protection, and reduces the "boot surge pulse" in the circuit.
