MP7770GF-Z

Overview

The MP7770GF-Z is a single-ended Class-D audio amplifier manufactured by Monolithic Power Systems. It delivers 45 W of output power into an 8-ohm load. The device operates within a supply voltage range of 9.5 V to 36 V and supports a total harmonic distortion plus noise (THD+N) of 0.05%. It features two channels, an analog input type, and a shutdown function. The component is housed in a TSSOP-EP-28 package with SMD/SMT mounting style. It functions within a temperature range of -40°C to +125°C and draws 3 mA during operation.

Feature Summary

• Class-D architecture for high-efficiency audio amplification
• Integrated thermal protection and short-circuit protection mechanisms
• Supports mono or stereo configurations via single-ended output topology

Applications

• Home theater systems
• Portable audio devices
• Automotive infotainment units

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-EP-28 package dimensions match your PCB footprint requirements. Ensure the design accounts for the 9.5 V minimum operating voltage and adequate heat dissipation for 45 W continuous output. Check for moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when a high-power, single-ended Class-D solution is required for 8-ohm loads. It is suitable for designs needing a wide input voltage range up to 36 V. Consider the TSSOP-EP-28 package for surface-mount applications requiring exposed pad thermal management. Verify that the 0.05% THD+N specification meets the audio fidelity requirements of the target application.

Part Context

This part belongs to the MP7770 series of audio amplifiers from Monolithic Power Systems. It is categorized under Audio ICs and specifically designed for high-power audio applications. The series focuses on delivering efficient sound reproduction with integrated protection features. It serves as a standalone amplifier solution for various consumer and industrial audio equipment.

Replacement Considerations

Consult official MPS documentation for direct pin-to-pin replacements. Cross-reference with other Class-D amplifiers in the same power class if availability is constrained. Ensure any substitute matches the 28-TSSOP-EP package and 36 V maximum voltage rating.
