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
Ideal for compact battery-powered speakers due to its low 2.5V to 5.5V supply range and high efficiency Class D operation, delivering 2.78W into 4Ω.
USB-Powered Desktop Speaker
Operates directly from a USB 5V rail, providing ample mono output for small desktop or laptop speakers with minimal heat generation.
Smart Home Intercom
The depop circuitry eliminates audible clicks during power-up, making it suitable for voice applications in smart home intercoms.
Alarm and Siren Driver
Short-circuit and thermal protection ensure reliable operation in alarm systems where continuous high-power output may be required.
Battery-Powered Toy Audio
Low quiescent current and wide voltage range allow direct connection to 2-cell or 3-cell battery packs in toys and gaming devices.
Line Driver for Audio Preamp
Can be configured as a line driver to boost low-level audio signals to line level for further processing or transmission.
