Product Overview

The LM3914V/NOPB is a Monolithic Integrated Circuit senses analogue voltage levels and drives 10 LEDs, providing a linear analogue display. A single pin changes the display from a moving dot to a bar graph. Current drive to LEDs is regulated and programmab...
  • Drives LEDs, LCDs or vacuum fluorescents
  • Bar or dot display mode externally selectable by user
  • Expandable to displays of 100 steps
  • Operates with single supply of less than 3V
  • Inputs operate down to ground
  • Output current programmable from 2 to 30mA
  • 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
  • Internal 10-step divider is floating and can be referenced to a wide range of voltages
  • Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
