LM3914N-1 Description

Short technical summary and product information.

The LM3914N-1 is a monolithic integrated circuit designed to sense analog voltage levels and drive 10 LEDs, providing a linear analog display. It offers external selection between dot and bar display modes. The circuit includes an internal adjustable voltage reference ranging from 1.2V to 12V and can operate with a single supply as low as 3V.

 

Key electrical specifications include an input voltage range down to ground, withstanding up to ±35V without damage. The output current is programmable from 2 mA to 30 mA, and the outputs are current-regulated open-collectors. This allows for flexible interfacing with TTL or CMOS logic.

 

The LM3914N-1 is expandable to displays of 100 steps by chaining multiple units. It is rated for operation from 0°C to +70°C and comes in a PDIP-18 package suitable for through-hole mounting.

 

This component is well-suited for applications such as analog meter circuits, visual alarms, and expanded scale functions. Its versatility allows it to drive LEDs of various colors or low-current incandescent lamps.
