  • Internal Voltage Reference from 1.2V to 12V
SKU: SLY-IC226-1 Category:

Product Description


  • 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.
  • The circuit contains its own adjustable reference and accurate 10-step voltage divider.
  • The low-bias-current input buffer accepts signals down to ground, or V −, yet needs no protection against inputs of 35V above or below ground.
  • The buffer drives 10 individual comparators referenced to the precision divider. Indication non-linearity can thus be held typically to ½%, even over a wide temperature range


  • 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 30mA
  • No Multiplex Switching or Interaction Between Outputs
  • Input Withstands ±35V without Damage or False Outputs
