Hot-selling and scarce MP7741DQ-LF-Z 10W Class D Mono Single Ended Audio Amplifer QFN

Product Descriptions

The MP7741 is a mono 10W Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following: 

z 250mΩ power MOSFETs

z Startup / Shutdown pop elimination

z Short circuit protection circuits

The MP7741 utilizes a single ended output structure capable of delivering 10W into 8Ω speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiencies. The circuit is based on the MPS’ proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.

MP7741 features programmable VDD shutdown voltage by controlling the UVP node voltage. The default VDD shutdown voltage is 8.4V if the UVP pin is NC.
