Overview
The MP7720DS-LF is a mono 20W Class-D single-ended audio amplifier from Monolithic Power Systems. It operates on a single supply voltage ranging from 9.5V to 24V and delivers 20W of output power into a 4Ω load at VDD = 24V. The device features an integrated 180mΩ power MOSFET, achieving 93% efficiency at full power. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.04% for 1W output into an 8Ω load. The switching frequency can reach up to 1MHz, and the typical input noise is 190µV.
Feature Summary
- Integrates 180mΩ power MOSFETs to significantly reduce solution size
- Includes dedicated startup and shutdown pop elimination circuits
- Features short circuit protection and thermal protection mechanisms
- Supports mute and standby modes for low power consumption
Applications
- Surround sound DVD systems
- Televisions
- Flat panel monitors
- Multimedia computers
- Home stereo systems
Procurement Notes
Verify the specific suffix against official MPS documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the operating temperature range aligns with your system's environmental constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring high-efficiency audio amplification in space-constrained applications. The single-supply operation simplifies power architecture compared to dual-supply alternatives. Consider the 1MHz switching frequency when designing EMI filters to ensure compliance with electromagnetic interference standards.
Part Context
This part belongs to MPS' second-generation fully integrated audio amplifier series. It is designed to replace traditional AB-class amplifiers by offering higher efficiency while maintaining high-fidelity audio performance. The integration of internal switches eliminates the need for external output capacitors in many configurations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official MPS documentation or authorized distributors for current alternative recommendations.
