www.digikey.com LM3916 Dot/Bar Display Driver General Description The LM3916 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing an electronic version of the popular VU meter. One pin changes the display from a bar graph to a moving dot display. LED current drive is regulated LM3914Dot/Bar Display DriverGeneral DescriptionThe LM3914 is a monolithic integrated circuit that sensesanalog voltage levels and drives 10 LEDs, providing a linearanalog display. A single pin changes the display from a mov-ing dot to a bar graph. Current drive to the LEDs is regulatedand programmable, eliminating the need for resistors.
Low Offset Voltage Dual Comparators 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 The LM3914 contains a ten-stage voltage divider, each stage when reached will illuminate the matching LED (and those below it in level meter mode). Let’s consider the most basic of examples (from page two of the data sheet) – a voltmeter with a range of 0~5V: The Vled rail is also connected to the supply voltage in our example.
