Product Description

The EV7782DF-01A is a stereo evaluation board for MPS’ MP7782 Class D Bridged Audio Amplifier. It is a second generation, fully integrated audio amplifier which dramatically reduces solution size by integrating four 180mΩ Power MOSFETs in a space saving TSSOP20 Package. It utilizes a full bridge output structure capable of delivering 40W into 8Ω speakers. As inallother 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 the MPS’ proprietary variable frequency modulation topology (patents pending) that delivers excellent PSRR, fast response time and operates on a single power supply.

IC Details

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.
