Datasheet Details

Part number:

LM4666

Manufacturer:

National Semiconductor

File Size:

642.74 KB

Description:

Filterless High Efficiency Stereo 1.2W Switching Audio Amplifier

Features

* an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces parts count, simplifies circuit design, and reduces board area. The LM4666 processes analog inputs with a delta-sigma modulation technique that lowers output noi
