产品描述

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.
