This is the LM3914 Dot/Bar display analog-controlled LED driver that uses an a linear output scale. With this driver all it takes is a single, analog signal to drive a string of 10+ LEDs, which can be configured into either bar mode (where all LEDs below a certain point turn on) or dot mode (with only a single LED on at a time). Hook them up properly, and you can create all sorts of nifty multi-LED displays.

The LM3914 is very easy to apply as an analog meter circuit. A 1.2V full-scale meter requires only 1 resistor and a single 3V to 15V supply in addition to the 10 display LEDs. If the 1 resistor is a pot, it becomes the LED brightness control. The simplified block diagram illustrates this extremely simple external circuitry.

Features:

  • Drives LEDs, LCDs or Vacuum Fluorescents
  • Bar or Dot Display Mode Externally Selectable
  • Expandable to Displays of 100 Steps
  • Internal Voltage Reference from 1.2V to 12V
  • Operates with Single Supply of Less than 3V
  • Outputs can Interface with TTL or CMOS Logic
