MP7745DF-LF-Z

The MP7745 is a Stereo 2 x 20W Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduces solution size by integrating the following: 250m? power MOSFETs Startup / Shutdown pop elimination Short circuit protection circuits The MP7745 utilizes a single ended output structure capable of delivering 20W per channel into 4? speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiencies. The circuit is based on the MPS’ proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.

2 x 20W Output at VDD = 24V into 4? load THD+N = 0.05% at 1W, 8? 93% Efficiency at 20W, 4? & VDD = 24V Low Noise (103µV Typical) Switching Frequency Up to 1MHz 9.5V to 26V Operation from a Single Supply Integrated Startup and Shutdown Pop Elimination Circuit Thermal and Short Circuit Protection Integrated Power FETs Pin Compatible with MP7722 and MP7742 Available in TSSOP20-Exposed Package
