Monolithic Power Systems, Inc. Audio Amplifiers MP7770GF-P

The MP7770GF-P is an analog class-D audio amplifier designed for versatile audio applications. It can operate in either a stereo single-ended configuration, delivering 45W per channel into 4,Ѷ speakers, or in a mono bridge-tied-load configuration, providing 90W into 8,Ѷ speakers, with a maximum supply voltage of 36V. The amplifier features integrated 100m,Ѷ power MOSFETs, startup and shutdown pop elimination, and short-circuit protection, ensuring reliable performance. With a total harmonic distortion plus noise (THD+N) of 0.03% at 1W into 8,Ѷ, the MP7770GF-P achieves over 90% efficiency at 10% THD, making it suitable for high-fidelity audio applications. It operates from a single power supply within a voltage range of 9.5V to 36V and can output a peak current of ¬±8.5A. The device also includes thermal and short-circuit protection features, output fault flag, and thermal warning indicators. The amplifier is packaged in a TSSOP28-EP format with an exposed pad, facilitating efficient thermal management. Typical applications include DVD receivers, mini combo systems, home theater systems, surround sound systems, and audio docking stations.
