EV7782DF-00A Datasheet, PDF (1/5 Pages) Monolithic Power Systems – 50W Class D Mono Bridged Audio Amplifier Evaluation Board

The Future of Analog IC Technology
DESCRIPTION
The EV7782DF-00A is the demo board for the
MP7782, a Mono, 50W Class D Audio
Amplifier. It is one of MPS’ second generation
of fully integrated audio amplifiers 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
50W into 6Ω 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 the
MPS’ proprietary variable frequency modulation
topology (patents pending) that delivers
excellent PSRR, fast response time and
operates on a single power supply.
