Bridgold 10pcs LM3914N-1 LM3914 Dot/Bar Display Driver 10-bit LED Driver,with Adjustable and programmable LED Current 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. Package include: 10pcs LM3914N
- Drives LEDs, LCDs or vacuum fluorescents
- Bar or dot display mode externally selectable by user
- Internal voltage reference from 1.2V to 12V
- Output current programmable from 2 mA to 30 mA
- Operates with single supply of less than 3V
