LM3914 Pdf资料

应用功能： Dot/Bar Display Driver The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors.This feature is one that allows operation of the whole system from less than 3V.
