MP8044DF-LF-Z

Overview

The MP8044DF-LF-Z is a Class-D stereo audio amplifier manufactured by Monolithic Power Systems. It delivers 20W of output power into a 4-ohm load and 8W per channel into an 8-ohm load. The device operates on a single supply voltage ranging from 7.5V to 22V. It utilizes a TSSOP-20 package for surface-mount installation. Key electrical characteristics include a THD+N of 0.07% at 1kHz, ensuring high-fidelity audio reproduction. The component supports short-circuit protection and thermal shutdown for robust operation in embedded electronics and industrial equipment applications.

Feature Summary

• High-efficiency Class-D architecture for stereo audio amplification
• Integrated short-circuit and thermal protection mechanisms
• Low total harmonic distortion plus noise for high-fidelity sound

Applications

• Embedded electronics systems requiring stereo audio output
• Industrial equipment with integrated audio interfaces
• Portable devices utilizing single-supply power architectures

Procurement Notes

Verify the specific suffix and packaging configuration against official Monolithic Power Systems documentation prior to ordering. Confirm that the TSSOP-20 footprint matches your PCB design constraints. Ensure compliance with RoHS standards as indicated in the manufacturer's specifications. Cross-reference the datasheet revision to validate pinout compatibility with existing designs.

Selection Notes

Select this component when a compact stereo solution is required within a 7.5V to 22V supply range. The TSSOP-20 package offers a balance between thermal performance and board space efficiency. Consider the 20W capability into 4-ohm loads for applications demanding higher volume output without external heat sinks. Verify that the input signal levels are compatible with the driver stage requirements.

Part Context

This part belongs to the MP804x series of audio amplifiers from Monolithic Power Systems. It is designed as a direct replacement for legacy stereo amplifier solutions in consumer and industrial markets. The series emphasizes high efficiency and low electromagnetic interference, making it suitable for battery-powered and noise-sensitive environments.

Replacement Considerations

Check for equivalent parts such as the MP8046DF-LF-Z if different power ratings or pinouts are acceptable. Verify that any substitute maintains the same TSSOP-20 package and operating voltage range to ensure mechanical and electrical compatibility.
