Product Description

The MP7705 is a stereo 2x5W/2x2.5W Class? Audio Amplifier. It is one of MPS?second generation fully integrated audio amplifiers which dramatically reduces solution size by integrating the following: ? 250mO power MOSFETs ? Startup / Shutdown pop elimination ? Short circuit protection ? Mute / Standby The MP7705 utilizes a single ended output structure capable of delivering 2x5W into 4O or 2x2.5W into 8O speakers. MPS Class? 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.
