| Part Number | Description |
|---|---|
| LM4664 | Filterless High Efficiency 1.1W Switching Audio Amplifier |
| LM4666 | Filterless High Efficiency Stereo 1.2W Switching Audio Amplifier |
| LM4667 | Filterless High Efficiency 1.3W Switching Audio Amplifier |
| LM4668 | 10W High-Efficiency Mono BTL Audio Power Amplifier |
| LM4610 | Dual DC Operated Tone/Volume/Balance |
The LM4663 is a fully integrated single supply, high efficiency Class D audio power amplifier solution. The LM4663 utilizes a continuous time delta-sigma modulation technique that lowers output noise and THD when pared to conventional pulse width modulators.
