About This Product

■Summary

MP7722 is a stereo 2 x 20W class D audio amplifier. This is one of MPS' second generation fully integrated audio amplifiers, which significantly reduces the size of the solution by integrating • 180mΩ power MOSFET • Pop noise rejection during startup/shutdown • Short-circuit protection on mute/standby. The MP7722 utilizes a single-ended output structure capable of delivering 220W to a 4Ω speaker. MPS' Class D audio amplifiers exhibit the high fidelity of Class A/B amplifiers with over 90% efficiency. The circuit is based on MPS' proprietary variable frequency topology, which provides low distortion, fast response time, and operates from a single supply.

■Features and benefits

・20W output at VDD = 24V into 4Ω load ・THD + N = 0.06% (1W, 8Ω) ・93% efficiency at 20W ・Low noise (190μV standard) ・Switching frequency up to 1MHz ・9.5V to 24V operation with single power supply ・Integrated pop noise removal circuit during startup and shutdown ・Thermal and short circuit protection ・Integrated 180mΩ switch ・Mute/standby mode (sleep) ・20-pin TSSOP package with thermally enhanced exposed pad

■Available product numbers

・MP7722DF-LF-P MP7722DF-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
