MP7752GF-Z

Overview

The MP7752GF-Z is a stereo BTL Class-D audio amplifier manufactured by Monolithic Power Systems. It operates within a supply voltage range of 5 V to 18 V and delivers 15 W per channel into an 8-ohm load. The device features a fixed switching frequency, analog input, and a gain of 36 dB. Total Harmonic Distortion plus Noise is rated at 0.08%. It includes shutdown functionality and operates between -40°C and +125°C in a 28-TSSOP-EP package.

Feature Summary

• Stereo bridge-tied load configuration for driving dual speakers
• Inductorless Class-D architecture for simplified design
• Integrated protection against short circuits and pop-and-click noise

Applications

• Portable audio devices requiring high efficiency
• Home theater systems with stereo speaker outputs
• Automotive infotainment audio channels

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status as per manufacturer declarations. Confirm the 28-TSSOP-EP package variant matches your PCB footprint requirements. Ensure thermal management solutions align with the junction temperature limits specified in the official datasheet for continuous operation.

Selection Notes

Select this component when a fixed-frequency, inductorless solution is required for stereo applications. Compare output power ratings against load impedance constraints. Verify that the 18 V maximum supply voltage suits the system power rails. Check compatibility with existing control logic for the shutdown pin interface.

Part Context

This part belongs to the MP7751/MP7752 family of Class-D amplifiers from Monolithic Power Systems. It shares architectural similarities with the MP7751 but offers adjusted power specifications. The series targets compact audio designs where board space is limited due to the elimination of external inductors.

Replacement Considerations

The MP7751GF-P is listed as a direct substitute within the same manufacturer portfolio. Verify electrical parameter alignment before substitution.
