The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. One pin changes the display from a bar graph to a moving dot display.

The LM3915 is a monolytthic IC designed to sense analogue voltage signals, and produce an incremental or sequential logic switching across its 10 output. Inidicating devices likes LEDs, LCD or vaccum displays can be attached with these outputs to obtain a corresponding visual indication in response to the varying input analogue signal.

Description: Dot/Bar Display Driver. Manufacturer: National Semiconductor (TI).
