EV7752-F-00A Evaluation Kit Inductorless 2x15W Stereo BTL Fix Frequency Class D Audio Amplifier Evaluation Board
The EV7752-F-00A is the evaluation board for the MP7752, a 15W stereo BTL Fix Freuquency Inductorless Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following:
- 240mΩ power MOSFETs
- Startup / Shutdown pop elimination
- Short circuit protection circuits
- Advanced EMI performance
- Inductorless topology
The MP7752 utilizes Bridge Tied Load output structure capable of delivering stereo 15W into 8Ω speakers. It features in automatic shutdown function which can save power in battery-used system. The PLIMIT function is useful for limiting total output power by simply adjust a DC reference voltage at PLIMIT pin. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiency.
