MP1720DH-216-LF-Z

Audio Amplifiers Overview

The MP1720DH-216-LF-Z is a Class-D audio amplifier manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.5 V to 5.5 V and delivers 2.78 W of output power into a differential load. The device features a fixed gain of 21.6 dB, a total harmonic distortion plus noise (THD+N) of 0.15%, and a slew rate of 200 V/µs. It functions in an ambient temperature range from -40°C to +85°C and draws 7 mA of operating current. The component is housed in a 10-pin MSOP package with exposed pad.

Audio Amplifiers Feature Summary

• Eliminates the need for external output LC filters while passing FCC radiated emission standards with extended cable lengths.
• Provides fully differential input capability to enhance noise immunity in audio signal paths.
• Integrates thermal shutdown and short-circuit protection mechanisms for operational reliability.

Audio Amplifiers Applications

• Portable multimedia devices requiring high-efficiency audio amplification
• Consumer electronics utilizing Class-D topology for low quiescent current
• Battery-powered systems needing minimal startup pop and low shutdown current

Audio Amplifiers Procurement Notes

Verify the specific suffix LF-Z indicates lead-free compliance and reel packaging configuration against the manufacturer's official documentation. Confirm that the DH variant corresponds to the MSOP-EP package type required for your PCB layout. Ensure the 216 gain designation matches the system's required signal amplification level before finalizing procurement orders.

Audio Amplifiers Selection Notes

Select this component when a fixed 21.6 dB gain is necessary for the audio chain. The MSOP-EP package offers a compact footprint suitable for space-constrained designs. Consider the 2.5 V minimum supply voltage for compatibility with single-cell battery applications. Verify that the 2.78 W output power rating aligns with the connected speaker impedance requirements.

Audio Amplifiers Part Context

This part belongs to the MP1720 series of Class-D audio amplifiers. The series offers multiple gain options and switching frequency configurations. The DH suffix specifically denotes the MSOP-EP package variant, distinguishing it from other package types within the same functional family.

Audio Amplifiers Replacement Considerations

MP1720DH-216-LF-P serves as a tray-packaged alternative with identical electrical characteristics. Other gain variants such as MP1720DH-3-LF-Z or MP1720DH-12-LF-Z are functionally compatible but provide different amplification levels.
