What is LM3914?

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.

How many segments can a LM3914 display?

Many LM3914s can be • Expandable to Displays of 100 Steps “chained” to form displays of 20 to over 100 segments. Both ends of the voltage divider are • Internal Voltage Reference from 1.2V to 12V externally available so that 2 drivers can be made • Operates with Single Supply of Less than 3V into a zero-centermeter.

What is the lm3914n-1 PDIP?

The LM3914N-1 is available in an 18-lead PDIP This feature is one that allows operation of the whole (NFK) package. system from less than 3V. The following typical application illustrates adjusting The circuit contains its own adjustable reference and of the reference to a desired value, and proper accurate 10-stepvoltage divider.

What is The LM3914 dot/bar display driver?

LM3914 Dot/Bar Display Driver Check for Samples: LM3914 Versatility was designed into the LM3914 so that 1FEATURES controller, visual alarm, and expanded scale functions 2• Drives LEDs, LCDs or Vacuum Fluorescentsare easily added on to the display system.
