Description and Introduction

Dot/Bar Display Driver 18-PDIP 0 to 70 The LM3914N-1/NOPB is a monolithic integrated circuit manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Function:** LED Driver (Linear)  
- **Display Type:** Bar/Dot  
- **Number of Segments:** 10  
- **Supply Voltage Range:** 3V to 25V  
- **Output Current per Segment:** 10mA to 30mA (adjustable)  
- **Reference Voltage Range:** Adjustable (1.2V to 12V)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** PDIP-18  

### **Descriptions:**  
The LM3914N-1/NOPB is a dot/bar display driver designed to drive LEDs, LCDs, or vacuum fluorescents in a linear analog display. It senses analog voltage levels and drives 10 LEDs in either a bar graph or moving dot display mode.  

### **Features:**  
- **Bar or Dot Display Mode** (selectable via pin 9)  
- **Internal Voltage Reference** (programmable from 1.2V to 12V)  
- **Low Standby Current** (typically 6mA)  
- **LED Brightness Control** (via external resistor)  
- **Wide Supply Voltage Range** (3V to 25V)  
- **Directly Drives LEDs** without external transistors  
- **TTL/CMOS Compatible Input**  

This IC is commonly used in battery level indicators, audio level meters, and other analog display applications.
