The MP1720 is a high efficiency Class-D audio amplifier. It utilizes a full bridge output structure capable of delivering 2.7W into 4? speaker. This device exhibits the high fidelity of a class AB amplifier with an efficiency of 90% which dramatically reduces solution size by integrating the following:
250m? power MOSFETs (VIN =3.3V)
Startup / Shutdown pop elimination
Short circuit /Thermal overload Protection The MP1720 features a pin-selectable 1MHz or 1.3MHz frequency control or can be synchronized to an external clock source. The flexible switching frequency and internal EMIreduction scheme eliminates the need for an output LC filter and passes emission standards without filter & with considerable cable. The MP1720 has five fixed gain options. MP1720-3: 3dB; MP1720-6: 6dB; MP1720-9: 9dB; MP1720-12: 12dB; MP1720-216: 21.6dB. The MP1720 is available in 10-pin MSOP-EP and 10-pin QFN packages.
Passes FCC-Radiated Emissions Standards with 24inch of Cable without output filter 2.7W Into 4? with 5V VIN @ 10% THD+N Up to 90% Efficiency Flexible Switching Frequency setting Low Noise (53µV Typical) with 3.3V VIN 15ms Start-up time Eliminates pop Low Quiescent Current (4mA @3.3V) Low Shutdown Current (0.1µA) Full Bridge Output Drive Fully Differential Input Short circuit Protection Thermal Shutdown
