MP8049SDU-LF-P

Overview

The MP8049SDU-LF-P is a quad-channel Class D audio amplifier manufactured by Monolithic Power Systems. It operates within an input voltage range of 5 V to 26 V and delivers up to 30 W of output power per channel into an 8-ohm load. The device utilizes a half-bridge topology and provides a peak output current of 5.5 A. It is housed in a 40-pin QFN package measuring 5x5 mm with an exposed pad for thermal management. The component supports operation across a junction temperature range from -40°C to 125°C.

Feature Summary

• Quad-channel architecture providing independent amplification for four audio channels
• Class D topology designed for high efficiency and reduced heat dissipation
• Integrated protection mechanisms including short-circuit and thermal shutdown

Applications

• Multi-speaker automotive infotainment systems
• Home theater and surround sound speaker arrays
• Professional audio equipment requiring multiple independent channels

Procurement Notes

Verify the specific suffix against official MPS documentation, as the provided model uses a 'P' suffix which may differ from the standard 'Z' variant found in public catalogs. Confirm RoHS compliance status and moisture sensitivity level directly with the manufacturer or authorized distributors before procurement. Ensure the ordering part number matches the exact package and tape-and-reel specifications required for your assembly process.

Selection Notes

Select this component when designing systems requiring four independent audio outputs from a single integrated circuit. The wide input voltage range accommodates various supply rails common in automotive and consumer electronics. Consider the 40-QFN package size and thermal requirements during PCB layout to ensure adequate heat dissipation for continuous high-power operation.

Part Context

This part belongs to the MP8049S series of audio amplifiers from Monolithic Power Systems. The series focuses on delivering high-performance audio amplification in compact packages suitable for space-constrained applications. The MP8049SDU-LF-Z is a closely related variant often cited in technical literature, sharing similar core electrical characteristics and packaging options.

Replacement Considerations

Publicly documented substitutes include the MP8049SDU-LF-Z. Verify pinout compatibility and electrical parameter equivalence with the original datasheet before substitution.
