DESCRIPTION

The EV7721DF-00A is the evaluation board for

the MP7721, a stereo 10W Class D Audio

Amplifier. It is one of MPS’ productions of fully

integrated audio amplifiers which dramatically

reduces solution size by integrating the

following:

 250mΩ power MOSFETs

 Startup / Shutdown pop elimination

 Short circuit protection circuits

 Mute / Standby

The MP7721 utilizes a single ended output

structure capable of delivering 2x10W into 8Ω

speakers. MPS Class D Audio Amplifiers exhibit

the high fidelity of a Class A/B amplifier at

efficiencies greater than 90%. The circuit is

frequency topology that delivers excellent

linearity, fast response time and operates on a

single power supply.
