MP1720DH - High-Efficiency Audio Amplifier

This page provides the datasheet information for the MP1720DH, a member of the MP1720 High-Efficiency Audio Amplifier family.

Datasheet Summary

Description

The MP1720 is a high efficiency Class-D audio amplifier.

It utilizes a full bridge output structure capable of delivering 2.7W into 4Ω speaker.

Features

  • a pin-selectable 1MHz or 1.3MHz frequency control or can be synchronized to an external clock source. The flexible switching frequency and internal EMIreduction scheme eliminates the need for an output LC filter and passes emission standards without filter & with considerable cable. The MP1720 has five fixed gain options. MP1720-3: 3dB; MP1720-6: 6dB; MP1720-9: 9dB; MP1720-12: 12dB; MP1720-216: 21.6dB. The MP1720 is available in 10-pin MSOP-EP and 10-pin QFN packages.

MP1720 2.7W, Mono Class-D, Low-EMI, High-Efficiency Audio Amplifier DESCRIPTION The MP1720 is a high efficiency Class-D audio amplifier. It utilizes a full bridge output structure capable of delivering 2.7W into 4Ω speaker. This device exhibits the high fidelity of a class AB amplifier with an efficiency of 90% which dramatically reduces solution size by integrating the following: ⚫ 250mΩ power MOSFETs (VIN =3.3V) ⚫ Startup / Shutdown pop elimination ⚫ Short circuit /Thermal overload Protection The MP1720 features a pin-selectable 1MHz or 1.3MHz frequency control or can be synchronized to an external clock source.
