MP7741DQ-LF-P

Overview

The MP7741DQ-LF-P is a monolithic D-class audio amplifier manufactured by Monolithic Power Systems Inc. It features a single-channel output configuration housed in a 10-QFN (3x3) surface-mount package. The device operates within a supply voltage range of 9.5V to 36V and delivers a maximum output power of 10W into an 8-ohm load. It includes integrated protection mechanisms such as pop-and-click elimination, short-circuit protection, and thermal shutdown. The component supports a junction temperature operating range from -40°C to 125°C.

Feature Summary

• Integrates pop-and-click elimination circuitry to suppress startup and shutdown noise artifacts during operation.

Applications

• Single-channel audio amplification systems requiring high efficiency
• Portable electronic devices utilizing D-class amplifier topologies

Procurement Notes

Verify the specific suffix designation when ordering, as packaging variations exist between tape-and-reel and cut-tape formats. Confirm that the requested part matches the exact manufacturer number for the QFN-10 package. Ensure compatibility with the specified 9.5V to 36V supply voltage requirements for the target application design.

Selection Notes

Select this component for applications requiring a compact, single-ended D-class solution with integrated protection features. Consider the 10W output capability at 8 ohms against the available supply voltage headroom. Evaluate the thermal performance within the -40°C to 125°C junction temperature range for the intended enclosure constraints.

Part Context

This component belongs to the MP7741 series of D-class audio amplifiers from Monolithic Power Systems. It shares the same core functional architecture and pinout compatibility with other variants in the family, differing primarily in packaging options and specific suffix designations. The series is designed for high-fidelity audio reproduction with minimal external component count.
