Product Description

The MP7782 is a mono, 50W Class-D Audio Amplifier. It is one of MPS' second generation fully integrated audio amplifiers which dramatically reduces solution size by integrating four 180mO power MOSFETs in a space saving TSSOP20 package. The MP7782 utilizes a full bridge output structure capable of delivering 50W into 6O speakers. As in all other MPS Class-D audio amplifiers, this device exhibits the high fidelity of a Class AB amplifier with an efficiency of 90%. The circuit is based on ADAM?(Analog Digital Adaptive Modulation), MPS' proprietary variable frequency modulation topology (patents pending) that delivers excellent PSRR, fast response time and operates on a single power supply.
