About This Product

■Summary

The MP7740 is a mono 15W class D audio amplifier. This is one of MPS' fully integrated audio amplifier products, which significantly reduces solution size by integrating: • 250mΩ power MOSFET • Pop noise rejection during startup/shutdown • Short circuit protection circuit. The MP7740 utilizes a single-ended output structure capable of delivering 15W to a 4Ω speaker. MPS' Class D audio amplifiers exhibit the high efficiency and high fidelity of Class A/B amplifiers. The circuit is based on MPS's proprietary variable frequency topology, which provides excellent linearity, fast response time, and operates from a single supply.

■Features and benefits

・15W output at VDD = 24V into 4Ω load ・THD + N = 0.05% (1W, 8Ω) ・90% efficiency at 15W & VDD = 24V ・Low noise (103μV standard) ・Switching frequency up to 1MHz ・9.5V to 36V operation with single power supply ・Integrated pop noise removal circuit during startup and shutdown ・Thermal and short circuit protection ・Power FET integration ・Pin compatible with MP7720 ・Available in a small 8-pin SOIC package

■Available product numbers

・MP7740DN-LF-P MP7740DN-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
