About This Product

■Summary

MP7705 is a stereo 2 x 5W/2 x 2.5W class D audio amplifier. It is one of MPS's second generation fully integrated audio amplifiers and significantly reduces solution size by integrating: 250mΩ power MOSFET, pop noise rejection during startup/shutdown, short circuit protection, mute/standby. The MP7705 utilizes a single-ended output structure capable of delivering 2 x 5W into 4Ω or 2 x 2.5W into 8Ω 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 low distortion, fast response time, and operates from a single supply.

■Features and benefits

・2 x 2.5W output, VDD = 12V (8Ω load) ・2 x 5W output, VDD = 12V (4Ω load) ・THD + N = 0.06% (1W, 8Ω) ・95% efficiency at 2.5W ・Low noise (190μV standard) ・Switching frequency up to 1MHz ・Single power supply operation from 9.5V to 12V ・Integrated start-up and shutdown pop noise elimination circuit ・Thermal and short circuit protection ・Integrated 250mΩ switch ・Mute/standby mode (sleep) ・20-pin TSSOP package with thermally enhanced exposed pad

■Available product numbers

・MP7705DF-LF-P MP7705DF-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
