LM3916 - Dot/Bar Display Driver

Description

The LM3916 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing an electronic version of the popular VU meter.

One pin changes the display from a bar graph to a moving dot display.

Features

  • 1.
  • 2 Fast Responding Electronic VU Meter.
  • Drivers LEDs, LCDs, or Vacuum Fluorescents.
  • Bar or Dot Display Mode Externally Selectable by User.
  • Expandable to Displays of 70 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 Curr.
