LM3915N-1 10-Segment Dot/Bar LED Display Driver

The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. One pin changes the display from a bar graph to a moving dot display. LED current drive is regulated and programmable, eliminating the need for current limiting resistors. The whole display system can operate from a single supply as low as 3V or as high as 25V.


  • 3 dB/step, 30 dB range
  • Drives LEDs, LCDs, or vacuum fluorescents
  • Bar or dot display mode externally selectable by user
  • Expandable to displays of 90 dB
  • Internal voltage reference from 1.2V to 12V
  • Operates with single supply of 3V to 25V
  • Inputs operate down to ground
  • Output current programmable from 1 mA to 30 mA
  • Input withstands ±35V without damage or false outputs
  • Outputs are current regulated, open collectors
  • Directly drives TTL or CMOS
  • The internal 10-step divider is floating and can be referenced to a wide range of voltages
  • Temperature operation: 0°C to +70°C
  • 18-pin MDIP package
