This mono audio amplifier delivers up to 825mW of continuous output power into an 8Ω load from a 5V supply. Operating from 2.7V to 5.5V, it is optimized for battery-powered portable devices. The integrated shutdown mode reduces power consumption to near zero, extending battery life. Thermal protection ensures reliable operation under fault conditions. Housed in a compact 8-SOIC package, it is ideal for space-constrained applications such as portable speakers, radios, intercoms, and alarm systems.
- High Output Power: 825mW into 8Ω at 5V ensures loud, clear audio for portable devices.
- Low Voltage Operation: 2.7V minimum supply enables direct battery operation without boost converters.
- Integrated Protection: Shutdown and thermal protection enhance system reliability and safety.
- Compact Package: 8-SOIC footprint saves PCB space in dense designs.
