MP7721数据手册MPS中文资料规格书

描述 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.
