Visão Geral
Description
- Output Power: Up to 3.7W into 4Ω (5V supply) or 2.3W into 8Ω.
- Efficiency: >90% (Class D topology).
- Supply Voltage: 2.5V–5.5V, suitable for battery-powered devices.
- Interface: I²C control for volume, gain, and shutdown.
- Protections: Thermal shutdown, short-circuit, and overcurrent protection.
- Package: 16-pin TSSOP (WE) for compact designs.
Ideal for portable speakers, smartphones, tablets, and IoT audio applications. Its low quiescent current (~2.2mA) extends battery life.
[For detailed specs, refer to the datasheet.]
