MP7770GF

Overview

The MP7770GF-Z is a dual-channel Class-D audio amplifier manufactured by Monolithic Power Systems. It delivers 45 W of output power per channel into an 8-ohm load. The device operates on a single-ended output configuration with a supply voltage range from 9.5 V to 36 V. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.05%, a maximum output current of 8.5 A, and a quiescent operating current of 3 mA. It functions within a temperature range of -40°C to +125°C and utilizes a TSSOP-EP-28 surface-mount package.

Feature Summary

• Class-D topology for high-efficiency audio amplification
• Dual-channel architecture delivering substantial power output
• Integrated shutdown control for power management

Applications

• Automotive infotainment systems
• High-fidelity home audio equipment
• Professional sound reinforcement speakers

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's datasheet to confirm compliance with RoHS directives and material declarations. Ensure the TSSOP-EP-28 thermal pad requirements are met during PCB layout to maintain the specified 125°C operating limit. Confirm that the input signal interface matches the analog specification provided in the official documentation before integration.

Selection Notes

Select this component when high power density and low distortion are required for dual-channel applications. The wide supply voltage range supports various automotive and industrial battery architectures. Evaluate the thermal performance of the TSSOP-EP-28 package against the expected ambient conditions to ensure reliable operation at maximum output levels without exceeding junction temperature limits.
