MP7758 is an inductorless, analogue input class-D audio amplifier that drives stereo speakers in a bridge-tied load configuration. It is a fully integrated audio amplifier which reduces solution size dramatically. It integrates 240mohm power MOSFETs and short-circuit protection circuits. The MP7758 features start-up/shutdown pop elimination, as well as advanced EMI performance. The device can pass EMC tests without an inductor. The device utilizes a stereo BTL structure capable of delivering 15W per channel into 8ohm speakers with a 16V power supply. MPS class D audio amplifiers exhibit the high fidelity of class-AB amplifiers with high efficiency. The MP7758 includes an internal circuit that allows the system to automatically shut down after the absence of an audio signal is detected. This feature is well-suited for energy-using products and battery-operated applications. The device offers an adjustable power limit (PLIMIT) function. The MP7758 is available in a TSSOP-28 EP package.
