DESCRIPTION
The EV7782DF-02 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 180m
Power MOSFETs in a space saving TSSOP20
Package. It utilizes a full bridge output structure
capable of delivering 40W into 8 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.
