The MP1720DQ-216-LF-P is a high-efficiency mono Class D audio amplifier designed for portable and battery-powered applications. Operating from 2.5V to 5.5V, it delivers up to 2.78W into a 4Ω load. Integrated depop circuitry eliminates startup transients, while short-circuit and thermal protection ensure robust performance. The compact 10-QFN package makes it ideal for space-constrained designs such as Bluetooth speakers, intercoms, and alarm drivers.
- High Efficiency Class D Operation: Minimizes power loss and extends battery life in portable devices.
- Integrated Depop Circuitry: Eliminates audible pops and clicks during power-up and shutdown.
- Comprehensive Protection: Short-circuit and thermal protection ensure reliable operation under fault conditions.
- Wide Supply Voltage Range: 2.5V to 5.5V allows use with single-cell Li-ion or USB power sources.
- Compact Package: 10-QFN (3x3mm) saves board space in dense designs.
Portable Bluetooth Speaker
