DESCRIPTION
The EV7722DF-00C is the evaluation board for
the MP7722. The MP7722 is a stereo 20W
Class D Audio Amplifier. It is one of MPS鈥?/div>
second generation of fully integrated audio
amplifiers which dramatically reduces solution
size by integrating the following:
鈥?/div>
180m鈩?power MOSFETs
鈥?/div>
Startup / Shutdown pop elimination
鈥?/div>
Short circuit protection circuits
鈥?/div>
Mute / Standby
The MP7722 utilizes a single ended output
structure capable of delivering 2x20W into 4鈩?/div>
speakers. MPS Class D Audio Amplifiers exhibit
the high fidelity of a Class A/B amplifier at
efficiencies greater than 90%. The circuit is
based on the MPS鈥?AAM
TM
proprietary variable
frequency topology that delivers excellent
linearity, fast response time and operates on a
single power supply.
