About This Product

■Summary

The MP7720 is a mono 20W class D audio amplifier. It is one of MPS's second generation fully integrated audio amplifiers and significantly reduces solution size by integrating: • 180mΩ power MOSFET • Pop noise rejection during startup/shutdown • Short circuit protection mute/standby. The MP7720 uses a single-ended output structure that can deliver 20W to 4Ω speakers. 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 excellent PSRR, fast response time, and operates from a single power supply.

■Features and benefits

・20W output at VDD = 24V into 4Ω load ・THD + N = 0.04% (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 start-up and shutdown pop noise elimination circuit ・Thermal protection ・Integrated 180mΩ switch ・Mute/standby mode (sleep) ・Available in small 8-pin SOIC and PDIP packages

■Available product numbers

・MP7720DP-LF MP7720DS-LF-P MP7720DS-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
