Filterless High Efficiency Stereo 1.2W Switching Audio Amplifier
p/pLM4666 Product Folder The LM4666 is a fully integrated 1.2W, stereo high efficiency (Class D) switching audio amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. The LM4666 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators.
This LM4666SDBD is an evaluation board designed to ease the evaluation and effort during the development of a circuit using the LM4666SD. It is an easy to use stand-alone board that requires power and GND, an input signal and an output load.
