Update: 29 September, 2023

The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. It has an adjustable reference voltage and an accurate 10-step voltage divider. The circuit can drive LEDs of many colors or low-current incandescent lamps. Multiple LM3914s can be chained to form displays of 20 to over 100 segments. The LM3914 is very easy to apply as an analog meter circuit.
