DESCRIPTION

The EV7740DN-01B is the evaluation board for

the MP7740, a stereo 15W Class D Audio

Amplifier. It is one of MPS’ products of fully

integrated audio amplifiers which dramatically

reduce solution size by integrating the following:

250mΩ power MOSFETs

Startup / Shutdown pop elimination

Short circuit protection circuits

The MP7740 utilizes a single ended output

structure capable of delivering 15W 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.
