## Overview

The Texas Instruments LM3915N-1 is a high-performance 10-segment LED display driver that delivers logarithmic 3dB step analog voltage sensing. It supports bar or dot display modes, operates on a wide 3V to 25V single supply, and features programmable LED current drive with robust input protection, making it ideal for professional-grade visual level indication.

## Description

The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 db/step analog display. One pin changes the display from a bar graph to a moving dot display. LED current drive is regulated and programmable, eliminating the need for current limiting resistors. The whole display system can operate from a single supply as low as 3V or as high as 25V.

## Features

- 3 db/step, 30 db range and drives leds, lcds, or vacuum fluorescents
- Bar or dot display mode externally selectable by user and expandable to displays of 90 db
- Internal voltage reference from 1.2V to 12V and operates with single supply of 3V to 25V
- Inputs operate down to ground and output current programmable from 1 ma to 30 ma
- Input withstands 35V without damage or false outputs and outputs are current regulated, open collectors
