General Description
The EV0066 is a 20W stereo evaluation board
featuring MPS’ MP7720 Class D Single Ended
Audio Amplifier. The EV0066 can deliver 20W
into a 4
load with a 24V input supply.
The MP7720 is a mono 20W Class D Audio
Amplifier. It is one of MPS’s second generation
of fully integrated audio amplifiers which
dramatically
reduces
integrating the following:
180m
power MOSFETs
Start up / shut down pop elimination
Short circuit protection circuits
The MP7720 utilizes a single ended output
structure capable of delivering 20W into 4
speakers. As in all other MPS Class D Audio
Amplifiers, this device exhibits the high fidelity
of a Class A/B amplifier at efficiencies greater
than 90%.
