20W Stereo Class D Single Ended Audio Amplifier
Learn about our Evaluation Kit
Product Description
The EV7722DF-00C is the evaluation board for the MP7722. The MP7722 is a stereo 20W Class D Audio Amplifier. It is one of MPS’ second generation of fully integrated audio amplifiers which dramatically reduces solution size by integrating the following:
- 180mΩ power MOSFETs
- Startup / Shutdown pop elimination
- Short circuit protection circuits
- Mute / Standby
The MP7722 utilizes a single ended output structure capable of delivering 2x20W into 4Ω 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’ AAMTM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.
Product Features
- 20W Output at VDD = 24V into a 4Ω load
- THD+N = 0.06% at 1W, 8Ω
- 93% Efficiency at 20W
- Low Noise (190μV Typical)
- Switching Frequency Up to 1MHz
- 9.5V to 24V Operation from a Single Supply
- Mute/Standby Modes (Sleep)
