How to use lm3914V
The LM3914V is very easy to apply as an analog meter circuit. A 1.2V full-scale meter requires only 1 resistor and a single 3V to 15V supply in addition to the 10 display LEDs. If the 1 resistor is a pot, it becomes the LED brightness control. The simplified Outputs block diagram illustrates this extremely simple or external circuitry. The simplified Outputs block diagram is below.

Frequently Asked Questions
What is LM3914V IC?
The LM3914V 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.
What is dot mode and display mode?
The Mode pin allows you to select between "bar" mode and "dot" mode. In bar mode, all LEDs sequentially turn on. So, if the signal voltage is near max, all LEDs should be on. In "dot" mode just a single LED is on at any time.
