LM393

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range−to−ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer, automotive, and industrial electronics.

Audio Visualizer With an LCD Display

“Welcome to my third Instructable. People love listening to music. It is as they say, music reflects our mood. And it is a spectacle to see music become ‘alive’ right before our eyes. Well, that’s what music visualization does …
