Overview
The MP8049SDU-LF-Z is a four-channel Class-D audio amplifier manufactured by Monolithic Power Systems. It operates within a supply voltage range of 5V to 26V and delivers up to 30W per channel into an 8-ohm load. The device features a peak output current capability of 5.5A and utilizes a 40-VFQFN package with exposed pad dimensions of 5x5 mm. It supports operation across a junction temperature range from -40°C to +125°C.
Feature Summary
- Four-channel D-class architecture for multi-speaker configurations
- Integrated thermal and short-circuit protection mechanisms
- Wide input voltage compatibility for flexible power designs
Applications
- Multi-speaker audio systems requiring independent channel control
- Portable devices utilizing high-efficiency amplification
- Automotive infotainment speaker drivers
Procurement Notes
Verify the specific suffix LF-Z against official MPS documentation to confirm lead-free status and RoHS compliance before procurement. Confirm the 40-QFN package type matches your PCB footprint requirements. Ensure moisture sensitivity level 2 handling procedures are followed during assembly to prevent package damage.
Selection Notes
Select this component when designing systems requiring four independent audio channels with high power output in a compact form factor. Evaluate the 5x5mm QFN package constraints against available board space. Consider the 5.5A peak current rating for driving low-impedance loads efficiently while maintaining thermal stability under continuous operation.
Part Context
This part belongs to the MP8049S series of audio amplifiers from Monolithic Power Systems. It represents a solution for high-density, high-power audio applications where multiple channels are needed without excessive board area consumption. The series focuses on integrating protection features directly into the amplifier structure.
Replacement Considerations
Consult official MPS substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully if considering non-MPS equivalents.
