MP1720DH-3-LF-P

Audio Amplifiers Overview

The MP1720DH-3-LF-P is a mono Class-D audio amplifier from Monolithic Power Systems. It delivers 2.7W output power into a 4Ω load at 5V supply voltage with 10% THD+N. The device features a BTL output structure and integrates 250mΩ power MOSFETs. It offers a fixed gain of 3dB, selectable via the suffix. Operating frequencies are configurable to 1MHz or 1.3MHz. The amplifier includes pop-and-click suppression, short-circuit protection, and thermal shutdown.

Audio Amplifiers Feature Summary

• High efficiency up to 90% with low static current consumption
• Integrated EMI reduction scheme allowing operation without output filters
• Pop-and-click suppression for silent startup and shutdown
• Comprehensive protection against short circuits and thermal overload

Audio Amplifiers Applications

• Mobile phones
• Tablets
• MP3 players
• Portable audio equipment

Audio Amplifiers Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging versus 'Z'. Confirm availability status as distribution channels may list limited stock. Ensure the 3dB gain configuration matches system requirements. Check RoHS compliance documentation. Validate lead times due to potential supply constraints.

Audio Amplifiers Selection Notes

Select this variant for applications requiring a fixed 3dB gain setting. Compare against other gain options like 6dB or 9dB if signal levels differ. Consider the MSOP-EP package for thermal performance. Evaluate the need for external LC filters based on EMI regulations. Verify compatibility with 1MHz or 1.3MHz switching frequencies.

Audio Amplifiers Part Context

This component belongs to the MP1720 series of high-efficiency Class-D amplifiers. The series is designed for portable devices requiring high fidelity and low electromagnetic interference. The DH suffix denotes the MSOP-EP package type. The LF designation indicates lead-free manufacturing compliant with environmental standards.

Audio Amplifiers Replacement Considerations

Direct substitutes include MP1720DH-3-LF-Z with identical electrical characteristics but different packaging. Other gain variants such as MP1720DH-6-LF-P or MP1720DH-9-LF-P offer alternative amplification levels within the same package.
