MP7720DP-LF

Overview

The MP7720DP-LF is a Class-D mono single-ended audio amplifier manufactured by Monolithic Power Systems. It delivers 20W of output power into a 4Ω load at a 24V supply voltage. The device integrates 180mΩ power MOSFETs and utilizes a proprietary variable frequency topology for high efficiency exceeding 90%. Key electrical parameters include a THD+N of 0.04%, a shutdown current of 1.5mA, and an operating temperature range from -40°C to +85°C. It operates on a single power supply ranging from 9.5V to 24V.

Feature Summary

• Integrates 180mΩ power MOSFETs to reduce solution size
• Eliminates pop-noise during startup and shutdown
• Includes short-circuit protection circuitry
• Features mute and standby control functions

Applications

• Single-speaker audio systems requiring high power output
• Portable devices utilizing single-supply architectures
• Applications demanding high-fidelity audio reproduction with low distortion

Procurement Notes

Verify the specific suffix (LF-P) indicates PDIP-8 packaging when ordering. Confirm RoHS compliance status through official datasheets. Ensure the supplier provides genuine MPS components to avoid counterfeit risks. Check for moisture sensitivity levels prior to soldering. Validate that the package type matches the PCB footprint requirements.

Selection Notes

Select this component for designs requiring a single-channel D-class amplifier with integrated power stages. The PDIP-8 package suits through-hole assembly processes. Consider the 20W power capability relative to the 4Ω load impedance. Evaluate the thermal performance within the specified operating temperature range. Verify compatibility with the system's single-ended input signal requirements.

Part Context

The MP7720 belongs to MPS's full-integrated series of audio amplifiers. It combines AB-class fidelity with D-class efficiency. The device simplifies design by integrating power MOSFETs and protection circuits. This integration significantly reduces the overall solution size compared to discrete solutions.

Replacement Considerations

MP7720DS-LF-Z is a direct pin-compatible alternative in SOIC-8 packaging.
