LM3914 Datasheet (Texas Instruments) - Dot/Bar Display Driver

LM3914, 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.
