## Overview

The LM3914N-1 is a versatile 10-bit LED driver IC that senses analog voltages and drives 10 LEDs in either dot or bar mode, selectable via a single pin. It features an internal voltage reference adjustable from 1.2V to 12V and programmable LED current from 2mA to 30mA, eliminating the need for external resistors. Ideal for low-voltage applications, this pack includes 10 reliable chips, perfect for prototyping or production.

## Description

The 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. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V. Package include: 10pcs *LM3914N
