Product Description

The MP7721 is a stereo 2 x 10W Class D Audio
Amplifier. It is one of MPS’ second generation
fully integrated audio amplifiers which
dramatically reduces solution size by integrating
the following:
250mΩ power MOSFETs
Startup / Shutdown pop elimination
Short circuit protection
Mute / Standby
The MP7721 utilizes a single ended output
structure capable of delivering 2 x 10W 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
based on the MPS’ proprietary variable
frequency topology that delivers low distortion,
fast response time and operates on a single
power supply.

10W Stereo Class D Single Ended Audio Amplifier EV Board

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 based on the MPS’ AAM^TM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.
