The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display.


  •  Drives LEDs, LCDs or vacuum fluorescents
  •  Bar or dot display mode externally selectable by user
  •  Expandable to displays of 100 steps
  •  Internal voltage reference from 1.2V to 12V
  •  Operates with single supply of less than 3V
  •  Inputs operate down to ground
  •  Output current programmable from 2 mA to 30 mA
  •  No multiplex switching or interaction between outputs
  •  Input withstands ±35V without damage or false outputs
  •  LED driver outputs are current regulated, open-collectors
  •  Outputs can interface with TTL or CMOS logic
  •  The internal 10-step divider is floating and can be referenced to a wide range of voltages
