Upgrade to myMPS+Product Description
The EV7748DF-00A is the evaluation board for the MP7748, a 2 x 20W stereo Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following:
- 250mΩ power MOSFETs
- Startup / Shutdown pop elimination
- Short circuit protection circuits
The MP7748 utilizes a single ended output structure capable of delivering 20W into 4Ω speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiency. The circuit is based on the MPS’ AAMTM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.
Product Features
- 2 x 20W Output at VDD = 24V into a 4Ω load
- THD+N = 0.02% at 1W, 8Ω, 1kHz
- 91% Efficiency at 20W and VDD=24V with 4Ω load
- Low Noise (103μV Typical)
- 9.5V to 36V Operation from a Single Supply
