MP7722DF-LF-Z

Overview

The MP7722DF-LF-Z is a stereo Class-D audio amplifier manufactured by Monolithic Power Systems. It delivers 20W per channel into a 4-ohm load with a supply voltage range of 9.5V to 28V. The device features a total harmonic distortion plus noise (THD+N) of 0.07%. It operates within a temperature range of -40°C to +85°C and utilizes a TSSOP-20 package for surface mount installation.

Feature Summary

• Stereo Class-D architecture providing dual-channel audio amplification
• High efficiency single-ended output configuration
• Low total harmonic distortion plus noise performance

Applications

• Portable audio devices requiring high power density
• Home theater systems utilizing single-ended speaker connections
• Automotive infotainment audio channels

Procurement Notes

Verify the specific suffix LF-Z against official MPS documentation to confirm lead-free status and RoHS compliance. Confirm the TSSOP-20 package type matches your PCB footprint requirements. Ensure the 9.5V to 28V supply voltage range aligns with your system design constraints before procurement.

Selection Notes

Select this component when a stereo Class-D solution is required for 4-ohm loads. The 20W per channel rating suits applications needing substantial output power in a compact form factor. Consider the TSSOP-20 package for space-constrained designs requiring surface mount technology.
