DESCRIPTION

The EV7742DF-00B is the evaluation board for

the MP7742, a stereo 15W Class D Audio

Amplifier. It is one of MPS’ products 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

The MP7742 utilizes a single ended output

structure capable of delivering 2x15W into 4Ω

speakers. MPS Class D Audio Amplifiers exhibit

the high fidelity of a Class A/B amplifier at high

efficiency. The circuit is based on the MPS’

that delivers excellent linearity, fast response

time and operates on a single power supply.
